- . the Ascendant-Descendant of this time straddles her natal Ascendant-Descendant. There is a Moon-Jupiter opposition straddling the IC-MC. The Moon is ruler of her natal 8th house and Jupiter is ruler of her Ascendant. This Moon-Jupiter-IC-MC configuration was square her Regiomontanus Part of Death at 16Taurus12.
- The cusp of the twelfth house is where the Ascendant was when 1/3 of this time had passed, the eleventh house cusp is where the Ascendant was when 2/3 of that time had passed. The cusps of houses 9 and 8 can be explained as Descendants for 1/3 and 2/3 respectively of this time span after birth.
The solar return Ascendant of a particular year falling in the 5th or 7th natal houses, or the natal Ascendant coinciding with the 7th house cusp (Descendant) in a solar return chart. (The latter could be indicative of a major year regardless of whether a marriage or a romantic relationship takes place.). The solar return set for the place where I’ll be when it happens has a Sagittarius/Gemini ascendant/descendant axis, with a concentration of personal planets in the 2nd-4th houses. However, when set for the place where I live, the new Leo/Aquarius ascendant/descendant axis shifts that concentration into the 5th-7th houses.

The following are indications of at least the potentialfor a romantic relationship, partnership, long-term commitment ormarriage. Some of these may be indications of business partnerships, orsimply attractions.
For a significant union of anything to occur, the charts of bothparties should have a number of factors activated. Those factors includeSun/Moon aspects, Venus/Mars aspects, and aspects involved with the rulerof the 7th and/or 5th houses, or with the natal Ascendant.
Marriage indicators in one chart do not necessarily mean they existin another person's chart. It may be apparent that there are majorconnections between two people in the natal chart (his Sun conjunct yourMoon, your Venus conjunct his Mars, etc.). Permanent unions, however,seem to occur when there are appropriate indicators in transits,progressions, and solar arc directions.
Before predicting for marriage or a relationship - or anything else- you should examine your natal chart to see what the natal chart saysabout your own attitudes toward relationships.
For example, are there strong indications that your chart suggestsindependence (Sun/Uranus, Venus/Uranus conjunctions, Mars/Pluto aspects),and will that work against you in the compromising and adjustmentsnecessary to share a life with someone else? How strong is Saturn in yourchart, because it can symbolize the endurance necessary for a long-termrelationship.
The 7th House
Look at the sign on the natal 7th house. It can tell you a lot aboutyour attitude toward others. This same attitude will likely prevailthrough any partnership that you might have. It may well be true that wefall in love with the same person over and over—they just have differentnames.
The 7th house cusp can say a lot about who that prototype personcould be. What are the aspects made by the 7th house ruler? If it'sVenus, for example, and Venus is conjunct, squaring or opposing Plutonatally, you may be attracted to dangerous partners, or people who createan intensity that might be difficult to sustain on a long-term basis. Oryou may pursue relationships that need to be kept secret. Pluto'sinvolvement also suggests that obsession may sometimes be mistaken for love.
If the 7th house ruler is Neptune, or if it resides there, and itis in challenging aspect to the Moon or Sun, you may find that youover-idealize potential partners, who can never live up to yourrose-colored view of them. This can ultimately set you up for disappointment.
|This essay is taken fromMichele Adler's book 'Predictive Astrology: Cycles of Change, Seasons ofMeaning' which can be ordered here.|
If Uranus is in challenging aspect to the ruler of the 7th, or ifUranus is in the 7th house, there is an initial excitement inrelationships that you expect to sustain over the long-term. You canbecome bored when that isn't the case. Uranus also indicates suddenseparations, which can end a relationship before it's off the ground. Astrong Uranian presence in a chart may also render a person far tooindependent for a committed long-term relationship.
The presence of Pluto in the 7th house or ruling it means one willlikely have to redefine a marriage or a partnership to make it work.(Some astrologers have observed that you never acquire the needssymbolized by the house in which Pluto resides - for example, Pluto inthe 7th seeks the intimacy of a powerful one-on-one relationship that itnever attains. I don't entirely agree with this observation. I think thenatal house where Pluto resides requires that you surrender yourexpectations about the matters of that house before you find peace withit. In some instances, this may mean giving up expectations of what youwant before you finally realize the joy of obtaining what you need.) Some people with very strong natal Pluto placements can be addicted tointensity and passion, and become easily disillusioned in a relationshipwhere they don't have it.
Many people want marriages or long-term commitments for reasonsother than love or companionship. A woman who seeks a partner forfinancial reasons may find one when her natal 2nd or 8th house or itsrulers are activated, as those are the money houses. A person who wishesto marry for status may do so, but it could be shown under an aspect tothe ruler of the 10th house or a planet in the 10th, which deals withstatus. In such cases, the ruler of the 7th may be making aspect bytransit or progression to the ruler of these 'motive' houses.
Author's Note: While the book's original text emphasizedaspects, declinations should also be taken into consideration. In thecase of people who marry for status, for example, there could well be adeclination of Venus and the Midheaven, or Jupiter and the Midheaven,either natally or in progressed declinations at the time of the marriage.
Most people don't keep track of the times when they meet otherpeople. However, most people usually remember the day of the meeting ofsomeone significant, and that is useful to a certain extent.
The following are some things that can hint of a more seriousrelationship in the making. (Please note that these are transits andprogressions for the time in which you meet someone, or when arelationship begins. This doesn't refer to natal aspects or to synastry.)
One of the other person's (OP) natal planets is conjunct oneof your directed or progressed planets at the time of themeeting. It is an interesting astrological quirk thatsignificant meetings tend to occur when a natal planet in one person'schart is conjunct a directed or progressed planet in another person's. Naturally, if you know the moment that you met, you can construct a chartand note what planets are affecting the Ascendant (in both your chart andthe OP's).
Transiting Jupiter is conjunct your natal Mars or Venus orthe OP's natal Mars or Venus. This can sometimes result in acertain giddiness or light-heartedness about the person. It can alsocoincide with a great deal of optimism about the other person. I would advise waiting until the Jupiter transit is over before assessing therelationship.
Transiting Saturn is trine your natal Mars or Venus or the OP's Mars orVenus. Whatever you choose to say about Saturn, its presence ina trine frequently means 'long-lasting.' It can also mean dutyand responsibility are involved. Or there could be a significant agedifference between you and someone else.
Progressed Venus or Mars is semi-sextiling anotherplanet. The progressed semi-sextile (30 degrees) is a time-honored aspect for its presence at the start of significantrelationships, whether it's the first time you meet or at the time of anactual union.
Progressed aspects involving the ruler of the natal 5th forromance, and the natal 7th for marriage or partnerships.Frequently a significant meeting will take place when the ruler of thenatal 5th is involved in a progressed aspect with the Sun, Moon, Venus,Mars or the Nodal axis.
Trines between Venus and Uranus can herald a sudden meetingwith someone exciting, but the permanence is in question due to Uranus'unpredictable and independent ways.
The progressed Sun aspecting the ruler of the 5th house (fora romantic relationship) or the 7th (for a permanentrelationship).
When the midpoints of natal and progressed planets areactivated, such as the midpoint of progressed Venus and natal Venus beingconjunct, opposing or squaring a natal or progressed planet in another'schart. (This is also true of the midpoints of the otherprogressed planets with their natal planets, such as the progressedMars/natal Mars midpoint, or progressed Sun/natal Sun midpoint, or progressed Ascendant/natal Ascendant.) The nature of the planet will state something about the relationship. If it involves Pluto, there can be an 'all-or-nothing' feel to the meeting; if it's on Uranus, the relationship may be off-and-on for many years; if it's on Mars, therecould be a strong sexual element initially.
When the natal Sun/Moon midpoint or progressed Sun/Moonmidpoint is activated. The Sun/Moon midpoint is an important midpoint forrelationships. If there is Ascendant involvement with thismidpoint ( someone's natal Ascendant conjunct your progressed Sun/Moonmidpoint, for example, or perhaps your progressed Sun/Moon midpoint aspecting someone else's natal or progressed Mars or Venus), there is a likelihood of meeting someone. Note that the converse progressed andconverse directed Sun/Moon midpoints can also be applied here.
When there is a progression activating the pre-natal solareclipse point in your chart or in the OP's chart. The pre-nataleclipse carries a fated quality with it. Progressions to it can sometimescoincide with life-changing events or meetings
The ruler of the natal 1st forming an aspect by transit orprogression to the ruler of the natal 7th. These can bechallenging or easy aspects.
Progressed or solar arc (SA) directed Moon conjunct thenatal Descendant or in the 7th house. The secondary progressed Moon will be conjunct the Descendant for about a month or more, and willbe in the 7th house for a little over two years. The solar arc directedMoon will stay on the Descendant for a year, and this will almost alwaysbring about a major life change. (Note: It may not be marriage or apartnership, despite the 7th house involvement.) The solar arc Moon movesone degree per year, so it will stay in your natal 7th house for a longtime. (This can also indicate a more public role for you, in addition topartnership implications.) The secondary progressed Moon stays in a housefor about 2-1/2 years, though there can be an overlap in the houses.
Author's note: The secondary progressed Moon in Libra istraditionally thought to be a good placement for a time in which arelationship develops. I think this may be true when the Moon is between00 and 10 degrees of Libra. As it moves into the Aquarian decanate (10-20degrees) and the Gemini decanate (20-30 Libra), it may be less likely.
Sextiles to natal Venus and progressed Venus or to the rulerof the natal 7th house. Sextiles present opportunities.
Progressed Mars conjunct someone's natal or progressed Venus, orprogressed Venus and natal or progressed Mars conjunctions. Thisis almost an astrological no-brainer. Venus and Mars are the attractionplanets. When there are powerful conjunctions, sparks usually fly. Thekeyword here is attraction. The permanence of these attractions isusually indicated by Saturn aspects.
The solar return for the year of meeting is heavy with Libraplanets. Note the converse solar return also. The solar returnMoon in Libra is a key indicator of a partnership opportunity during theyear, especially if it occupies the 1st, 4th, 7th or 10th houses. Librarising in a return chart is also an indicator. (If you have Libra risingin a solar return, find the lunar return after your birthday that alsohas Libra rising to hone in on the time frame for an important meeting. You can hone this down even further by noting what time of the year youwill have Libra rising in the diurnal charts.*)
The solar return Venus or Mars tied with the natal Sun/Moonmidpoint or the solar return's Sun/Moon midpoint. Remember thatif Venus and Mars are in the solar return, they are part of the year'stransits. The tie to the midpoint is usually a conjunction. The opposition, square, semi-square or sesquiquadrate aspect might alsoindicate a relationship, but one that has an obvious set of challengesfrom the beginning.
Progressed planets moving into the natal or progressed 7thhouse can coincide with important meetings, particularly if the planet isVenus or Mars or the Sun or Moon.
Solar eclipses and New Moons in the natal or progressed 5thor 7th houses. An eclipse in the 5th or 7th house accentuatesrelationship matters. (This is true even if you're alreadymarried. An eclipse can certainly challenge weak spots in a marriage if it falls in the 7th house. A 5th house eclipse can indicate the birth ofa child, a guarantee of changing any relationship. ) The New Moon is lesspotent than a New Moon (solar) eclipse. However, it may conjunct, opposeor square a progressed or directed planet, as well as a converseprogressed or directed planet. In this case, it becomes a lightning rodfor the matters of that planet. If the planet is connected with the 5thor 7th houses, it will affect relationships. This also applies to planetsin the solar return and the converse solar return.
Author's note: A Full Moon or a Full Moon Lunar Eclipse is not,in my opinion, as powerful as the solar eclipse. But Full Moons can bringthings to fruition. A Full Moon Eclipse does not usually end arelationship, but it can change it significantly.
Solar Return activated 2nd house. Some years back,I tested a large number of solar return charts of men for the year inwhich they married. In most cases, it was the second house that was activated, no doubt acknowledging that most men were contemplating their changed financial picture upon marriage, and their role in supporting afamily. This may not be the case now, as many households have two-careercouples. But an activated SR 2nd house can occur in years of importantmeetings that lead to permanent unions.
Mercury appears to be active where couples have a good understanding ofone another. While Venus and Mars may certainly attract and keepsparks going, Mercury contacts seem to be what keeps a relationship goingonce the sexual attraction has subsided. Progressed Mercury aspects seemto occur around the time that people meet who can become great friends,whether married or not. Broadly vice monthly horoscope scorpio. A progressed Mercury conjunct the other person'sAscendant can be a major indicator of a long friendship.
Activation of the progressed or natal Ascendant in eitherperson's charts usually occurs at a meeting or during the year that therelationship is developing. It is an old astrological axiom thatno relationship ever becomes permanent unless there are significantaspects to the Ascendants of the involved individuals. However, the progressed Ascendant can often be part of this axiom. Frequently one meets significant others at equally significant progressed times.
The solar return Ascendant of a particular year falling inthe 5th or 7th natal houses, or the natal Ascendant coincidingwith the 7th house cusp (Descendant) in a solar return chart. (The lattercould be indicative of a major year regardless of whether a marriage or aromantic relationship takes place.)
The diurnal Ascendant* or Descendant for the day of ameeting is tied to a significant transiting, progressed or directedplanet. The diurnal Ascendant and Descendant will conjunct the natal, progressed and directed planets once each year. In addition, the 5th and 7th house cusps of the diurnal chart will be conjuncting aprogressed or directed planet at least once a year. The diurnals can bevery revealing of specific days when some important meetings can occur.
Nodal involvement in your own chart or with planets insomeone else's. Among the many definitions of the North Node/ South Nodeis that of connections. While that can manifest on many different levels, it can also manifest in relationships. If you meetsomeone when either of you has progressed or directed planets conjunctthe other's Nodal axis, you may feel instantly 'connected' withthis individual. I have noticed in some cases that South Node connectionswith planets in someone else's charts can occasionally manifest aslong-term connections. I have seen Saturn/South Node involvement inrelationships that have spanned over 45 years. However, the individualswere not in constant contact with each other. One instance was of twopeople who managed to keep getting together every 10 years or so,coinciding with endings of marriages to other people. I put this in the'go figure' category.
Diurnal Ascendants.* Ascendants of both parties canalso be making interesting aspects on the day that they meet for thefirst time. This can be especially true if the diurnal is also conjunct aprogressed, directed or natal planet or angle. It is not uncommon fordiurnals to be swapped: for example, you have six degrees of Capricornrising on your diurnal, and the other person has six degrees of Cancerrising on his/her diurnal on the day you meet.
Specific Charts for Relationships
There are a number of relationship chart options available on mostsoftware. The composite chart is probably the best known. It iscomposed of the combined midpoints of each person's planets and angles. Ihave not worked with this chart for prediction possibilities. I haveheard other astrologers say that it is useful for understanding thepurpose of the relationship.
The chart of the moment that two people meet
As mentioned earlier, it's not often that anyone has exact data forthis chart. If you do have it, it can be as sensitive to transits,progressions and eclipses as any natal chart.
(Author's note: Since this book was written, I have heard ofanother technique similar to this. In The Mountain Astrologer(April/May 2019) there is a fine article called 'A Mystic Looks atAstrology' by Ray Grasse (p.40), and is taken from his book onmystic/occultist Shelly Trimmer, which is entitled 'An Infinity ofGods.' Trimmer suggests that if a person comes into your life, markthe exact moment it happens and then move your horoscope to that exactmoment. 'For instance, let's say the Ascendant right then is 10Taurus. Move your own chart around so that 10 Taurus is on the Ascendant.Now you can tell what this person means to you,' he says.)
The chart for the marriage
This is a very useful chart. It can foretell a number ofthings about the marriage and, like the meeting chart, it is sensitive totransits and progressions.
Example: A couple that I know married under a Moon-Pluto opposition.It symbolized the constant struggle in their marriage between the brideand her mother-in-law, as they occupied the same household for manyyears.I know that electional astrology can identify good times for the wedding,but there will be challenging aspects in any selected time. (Theastrologer has to pick the time when things look best, usually having towork within a certain time span in which the wedding can take place.)
A diurnal chart is done each day as if you were born on that day.If, for example, you wish to have a diurnal chart for, say, Nov. 23,2018, you would enter the data using that date and year. All other datawould be from your birth. You would set this date with the time of yourbirth, the place of your birth, and the time zone of yourbirth. You will have the same Ascendant, or close to it, each day of eachyear. But the transiting planets will be different, as will theprogressed. So perhaps you have a diurnal Ascendant on Nov. 23 every yearat 5 Taurus. But once every 12 years, transiting Jupiter will beconjunct that Ascendant. Or you may have the progressed Sun or ProgressedMoon conjunct that Ascendant. Or once every 84 years, you will haveUranus on the Ascendant! Those will be important days, and many can be significant for a relationship. The diurnal chart's house cusps will also conjunct progressed and directed planets throughout the year and can mark significant days. Because of the sensitivity of house cusps, I recommendusing the Koch house system for diurnal charts.

© 2019 - Michele Adler - InfinityAstrological MagazineOverview: Available house systems in the Extended Chart Selection
The following house systems can 'Extended Chart Selection' be used:
The Pacidus house system divides the phases of planetary and star movement above and below the horizon into equal-sized parts. A planet onthe cusp of the twelfth house, for example, has already passed 1/6 of itsso-calleddiurnal arc, a planet on the eleventh house cusp 2/6, a planet on the MC3/6or half of its diurnal arc, etc. The houses below the horizon divide the so-called 'nocturnal arc' of the stars and planets.
So, the Placidus system divides celestial movements and is consequentlyconsidered a time-oriented system.
For mathematical reasons, Placidus houses cannot be calculated for regions beyond the polar circles.
The Placidus house system is named after the Italian monk andmathematicianPlacidus de Titis (1603-1668), but was invented by the astronomer and mathematician Giovanni Antonio Magini (1555-1617).

The Koch house system (also called 'house system of the birth place')isdefined by horizon lines at different times on the day of birth. Wecalculatethe timespan that the MC zodiac degree has spent above the horizon sinceitsrising. The cusp of the twelfth house is where the Ascendant was when 1/3ofthis time had passed, the eleventh house cusp is where the Ascendant waswhen2/3 of that time had passed. The cusps of houses 9 and 8 can be explainedasDescendants for 1/3 and 2/3 respectively of this time span after birth.
Therefore, the Koch house system assigns special significance to the MC-ICaxis, because the measure of the division is predefined by the diurnal arcof the zodiacal degree of the MC at birth. Like Placidus, the Koch systemdivides celestial movements and is therefore considered a time oriented system.
For mathematical reasons, Koch houses cannot be calculated forregions beyond the polar circles.
The house system is named after the German astrologer Walter Koch(1895-1970)but was actually invented by Fiedrich Zanzinger (1913-1967) and HeinzSpecht (1925-).

The Campanus house system divides the celestial space above and belowthe horizon like an orange into twelve equal segments. The 'axis' of the'orange' lies on the horizon and is aligned from north to south. So, the division into twelve segments happens on the 'prime vertical', i.e. the great circle that runs through the East point, the zenith, the West pointand the nadir. The places where the segments or 'slices' of the 'orange' intersect the zodiac, make up the Campanus house cusps.
The Campanus system divides space and is therefore considered aspace-oriented house system.
The house system is named after the Italian mathematician Campanus ofNovara(1220-1296).
More information can be found in theAstro Wiki
The Regiomontanus house system divides the celestial equator intotwelve equal segments. Then, great circles are drawn from the North pointthrough these segment points to the South point. The intersection of theselines with the ecliptic (zodiac) make up the house cusps according toRegiomontanus. So, the sky is - similar to the Campanus system - divided like an orange, but the different segments of the 'orange' have differentsizes.
The Regiomontanus system is considered a house system defined by space.
The house system is named after the German mathematician, astronomerand astrologer Regiomontanus (Johannes Müller of Königsberg, 1436-1476),but was invented by the Spanish Jewish astrologer Abrahma ibn Esra(-1167).

The equal house system defines the Ascendant as the cusp of the firsthouse. Each house has the same size ('equal') of exactly 30°.The 10th house cusp therefore does not coincide with the MC but is squareto the Ascendant and consequently the highest point of the zodiac abovethe horizon.
The equal house system has been in use since the time of antiquity.

This house system places the MC exactly on the cusp of the 10th house.Each house has the same size ('equal') of exactly 30°. The Ascendant doesnot usually coincide with the cusp of the 1st house.
More information can be found in theAstro Wiki
The Vehlow house system belongs to the equal ('same size') housesystems.Here, the Ascendant is placed exactly in the middle of the first house.Ascendant and MC therefore do not coincide with a house cusp.
The Vehlow house system is named after the German astrologer Johannes Vehlow (1890-1958).
Whole Sign Houses
The Whole Sign house system considers the whole sign of the zodiac that contains the Ascendant as the first house. The following zodiac sign is the second house and so on. Here, houses are always complete zodiacsigns.The Whole Sign houses belong to the group of equal ('same size') houses.The Whole Sign house system has been in use since antiquity and iscurrentlyespecially popular in Indian siderean astrology.
Whole sign houses, 1. house = Aries
The first house begins at the cusp of Aries, all houses have the samesize ('equal'), and each house covers a whole zodiac sign.
Similar to the Campanus system, the Meridian system resembles a well-proportioned 'orange' but with the difference that the axis of this'orange' is not placed on the horizon but runs through the celestialpoles.In fact, the celestial equator is divided into 12 equal-sized segmentsstarting at the Meridian. Then, Meridian circles are drawn through thesesegment points. The Meridian house cusps are created by the intersectionsof these circles with the ecliptic.
The MC in the Meridian house system is identical with the 10th house cuspbut the Ascendant is not identical with the cusp of the 1st house.
The Meridian system can be interpreted as a time-oriented as well as space-orientedsegmentation of the celestial sphere. Each segment of the 'orange' coversexactly 30° and exactly 2 hours in sidereal time.
The Porphyry house system creates the intermediate houses by dividingeach of the four quadrants into three equal-sized segments.
The house system traces back to the ancient philosopher and scholarPorphyry (233-305?).
Astrological Cusps Can Be Ascendant Descendants 3
The Alcabitius house system divides the diurnal arc of the Ascendantinto six equal-sized segments. Then, Meridian circles are drawn throughthe resulting segments. The places where the circles intersect the ecliptic mark the cusps of the Alcabitius houses. The other house cuspscan be calculated by adding 180° respectively. Alternatively, thenocturnalarc can be divided into six parts and Meridian circles drawn through theresulting segments.
In this method, the Ascendant and MC are identical with the 1st and 10th house cusps.
The Alcabitius house system assigns particular significanceto the Ascendant-Descendant axis, because the measure of division is givenby the diurnal arc of the zodiacal degree of the Ascendant at birth.
The house system goes back to the Arab astrologer Abd al-Aziz ibn Uthmanal-Qabisi (lat. Alcabitius †967).
In this house system, first a vertical great circle is drawn throughAscendant, Zenith, Descendant and Nadir. This is then divided into 12equal-sized segments, and Meridian circles are drawn through the resultingsegment points. The house cusps result from the intersections of the Meridian circles with the ecliptic.
In this method, Ascendant and MC are identical with the 1st and 10th house cusps.
This house system was invented by three astrologers independently of each other: the Pole Bogdan Krusinski (1995), the Czech Milan Pisa (1994)and the Swiss Georg Goelzer (1993).
More information is found in the Documentation of the Swiss Ephemeris, chapter 6.1.13.
The horizon house system divides the sky according to the fourcardinal directions. The cusp of the 1st house is exactly due East, the10this exactly due South. The celestial sphere is divided into 12 segments,likean orange (similar to the Campanus and Meridian system), with the axis ofthe orange running through the Zenith and Nadir, and its 'equator'resting on the horizon. The house cusps result from the intersections ofthetwelve segments with the ecliptic.
In the horizon house system, the 10th house cusp is identical with the MC,but the 1st house cusp is not identical with the Ascendant.
In the Morinus system, the celestial equator is divided into twelveequal-sized segments starting from the Meridian. The segment pointson the equator are then converted to the ecliptical coordinate system.The ecliptic longitudes of these points make up the twelve house cusps.
In the Morinus house system the 10th house cusp deviates slightly fromthe MC. Similarly, the 1st house cusp is not identical with the Ascendant.
The house system is named after the French philosopher, mathematician andastrologer Jean-Baptiste Morin (Latin: Morinus, 1583-1656).
An article on Morin's Method of Determination (not his house system!)can be foundhere
The Polich-Page house system (also 'topocentric house system') ismathematically defined as follows: The tangent of the polar elevations ofthe intermediate houses corresponds to one or two thirds respectivelyof the tangent of the polar elevation of the Ascendant, i.e. thegeographiclatitude of the birth place. The individual house cusps are placed on the great circles which intersect the celestial equator at intervals of 30° respectively. In low and middle latitudes, topocentric house cusps tend todiffer from Placidus house cusps by less than one degree. Only closer toand beyond the polar circles, the differences become more pronounced.
Beyond the polar circles, the Polich-Page house system sometimes generates absurd and impractical house positions.
The house system was invented by the Hungarian-Argentinian astrologerWendel Polich (1892-1979) and the English-Argentinian astrologer AnthonyNelsonPage (1919-1970) erfunden.

What If Your Ascendant Is On The Cusp
The diurnal arc and the nocturnal arc of the Ascendant are divided intoequal-sized segments respectively. Then great circles are drawn fromthe North point through the segment points to the South point. Theintersections of these circles with the ecliptic mark the APC house cusps.
In the APC house system, the 1st house cusp is identical with theAscendantand the 10th house is conjunct the MC. However, it needs to be mentionedthat the house cusps 12-6, 11-5, 2-8, and 3-9 are not exactly oppositeeach other.
The house system was introduced by the Dutch astrologer Leo Knegt(1882-1957) and is used by the DutchWerkgemeenschap van Astrologen (WvA, aka “Ram school”).
Pullen SD (Neo-Porphyry)
The house system Pullen Sinusoidal Delta (also known asNeo-Porphyry house system) determines the house sizes from a sinusfunctiondepending on the size of the quadrants. You can find more detailedinformation on the mathematical process in the Documentation of the Swiss Ephemeris,chapter 18.104.22.168.
One peculiarity of this house system is the fact that when a quadrant issmaller than 30°, the middle house of the quadrant takes the size 0.
The house system was invented in 1994 by the American astrologer WalterPullen(born 1971), the author of the astrology software Astrolog.
The house system Pullen Sinusoidal Ratio determines the house sizesfrom a sinus function depending on the size of the quadrants. You can find more detailed information on the mathematical process in the Documentation of the Swiss Ephemeris,chapter 22.214.171.124.
The house system was invented in 2016 by the American astrologer WalterPullen (born 1971), the author of the astrology software Astrolog, andshould replace the house system Pullen SD.
The Sripati house system first calculates the house cusps accordingto Porphyry, i.e. each quadrant is divided into three equal-sized houses.Then the cusp of each house is moved to the middle of the previous house.
In this house system, the Ascendant and MC are not identical with the cusps of houses 1 and 10.
The Sripati house system originates in Indian Astrology.
Can Your Ascendant Be On The Cusp
Carter (poli-equatorial) house system
In this house system the celestial sphere is divided into an 'orange'with 12 commensurate segments. The axis of this orange runs through thecelestial poles, whereas its 'equator' comes to lie on the celestial equator (hence the name 'poli-equatorial'). Therefore, the house cuspslie on the Meridians. The Meridian of the 1st house cusp runs throughthe Ascendant. The Meridians of the other house cusps follow at intervalsof 30° each.
In this house system, the 1st house cusps is identical with the Ascendant,butthe 10th house cusp is not identical with the MC.
Astrological Cusps Can Be Ascendant Descendants
The house system was invented by the English astrologer Charles Carter (1887-1968).
The Sunshine house system divides both the diurnal and the nocturnalarcsof the Sun into six commensurate segments. Then, great circles are drawnfrom the North point through the segment points to the South point. Theintersections of theses circles with the ecliptic mark the Sunshine housecusps.
In the Sunshine house system, the cusp of the 1st house is identical with the Ascendant, and the 10th house cusp is identical with the MC. However, the house cusps 12-6, 11-5, 2-8, and 3-9 are not in exact opposition.
The house system was invented by the American astrologer Bob Makransky (born 1947).
This is the “house” system used by the Gauquelins and their epigones and critics in statistical investigations in Astrology. Basically, it is identical with the Placidus house system, i.e. diurnal and nocturnal arcs of ecliptic points or planets are subdivided. There are a couple of differences, though.
What Is Ascendant And Descendant In Astrology
- Up to 36 “sectors” (or house cusps) are used instead of 12 houses.
- The sectors are counted in clockwise direction.
- There are so-called plus (+) and minus (–) zones. The plus zones are the sectors that turned out to be significant in statistical investigations, e.g. many top sportsmen turned out to have their Mars in a plus zone. The plus sectors are the sectors 36 – 3, 9 – 12, 19 – 21, 28 – 30.
- More sophisticated algorithms are used to calculate the exact house position of a planet (see chapters 6.4 and 6.5 on house positions and Gauquelin sector positions of planets).
