How to Calculate the Formulas
Cece Stevens


There are two primary methods: numerical, and spatial. The numerical method is based on inserting the degree of the mentioned planet/point into the formula in the proper place, and completing the calculations. In the numerical method, there are two ways to convert the degrees for calculation. The simplest way
is to use the following table to convert the degree to a proper numeral. To do this, use the number given for the relevant sign, then add the actual degree within the sign. This, of course, is based on the 360 degree circle. No number is allowed to go over 360 or below 0. Any number which does, must either have
360 added or subtracted to give a working number which falls within the specified range (0-360).
Use Equal house Campanus system.

1.  Aries = 0
2.  Taurus = 30
3.  Gemini = 60
4.  Cancer = 90
5.  Leo = 120
6.  Virgo = 150
7.  Libra = 180
8.  Scorpio = 210
9.  Sagittarius = 240
10. Capricorn = 270
11. Aquarius = 300
12. Pisces = 330
The traditional way to convert the degrees, and the way I actually learned,is somewhat more cumbersome and confusing for students, given that a single "number" is comprised of portions in several difference bases. I will give a brief example, and leave the details to those who really want to explore the
subject. For example, to calculate the Part of Marriage in my chart using the formula

Asc + H7 - Venus.

Asc = 26 Cancer 46
H7 = 26 Capricorn 45
Venus = 16 Cancer 17
This could be written as:
   26 Cancer 45         Ascendent
+ 26 Capricorn 44  +   7th House
- 16 Cancer 17   - minus = PART OF MARRIAGE

Using the traditional method of calulation, sign is assigned a number of 0-11on a scale of 12. The degrees remain in a base of 30 (30 degrees per sign), and the seconds of arc are of course 60 per degree. Thus, this could also be written as:


   116.45
+ 296.45
- 106.17 = 307.30 = 7 Aquarius 30

The trick with this is to remember when moving between signs, degrees, and seconds, to carry and subtract in the appropriate base for that portion of the "number." So, if you add the first two "numbers," the seconds add up to 90; you must subtract 60, leaving 30, and carry the number 1 over to the degree
column. The advantage of this method is that you can, without performing the calculations, rapidly get a good idea of the sign and house location of the final result, simply by performing a rough calculation based on the houses, and a bit of the degrees. Naturally, to use in a proper delineation, one must have the
accurate result to use with transits, directions, and progressions. (NOTE: Trying to calculate arabic parts is basically useless unless one has a rectified chart for the native.) However I have also added what is also believed to work when ascendent is not known.

To calculate a formula using a spatial method, also known as the method of the ancients, is very different, and will give different results based on your preferred house system. Be forewarned. A simplistic approach would be to overlay a transparent copy of your chart, with the subtracted planet/point on the
natal Asc, and then mark the location of the added planet/point. This is for working purposes only.

For further consideration I am adding the points for your future reference.

FORTUNA:                Asc +   Moon        - Sun
COMMERCE:           Asc +   Mercury - Sun
MARRIAGE:             Asc + 7th House   - Venus
LOVE:                   Asc +   Venus       - Sun
PASSION:                Asc +   Mars        - Sun
INCREASE:           Asc +   Jupiter     - Sun
DIVORCE:                Asc +   Venus       - 7th House
FATALITY:               Asc +   Saturn      - Sun
CATASTROPHE:        Asc +   Uranus      - Sun
TREACHERY:          Asc +   Neptune - Sun
ORGANIZATION:       Asc +   Pluto       - Sun
SPIRIT:                    Asc +    Sun     - Moon
FAITH:                     Asc +    Mercury - Moon
FEMALE CHILDREN:        Asc +   Venus       - Moon
MALE CHILDREN:      Asc +   Jupiter     - Moon
MERCHANDISE:        Asc +   Fortuna - Spirit
SORROW & IMPRISONMENT:  (see Merchandise)
LIFE:                   Asc +   Moon    - Full Moon (just prior to birth)
MOTHER:             Asc +   Moon        - Venus (also friends)
FATHER:             Asc +   Sun     - Saturn
INHERITANCE:                 Asc +  Moon        - Saturn
SICKNESS:               Asc +   Mars        - Saturn
SIBLINGS:               Asc +   Jupiter     - Saturn
JOURNEY BY WATER:                Asc +  15' Cancer  - Saturn
TRAVEL BY LAND:         Asc +   9th House   - Lord 9th
PRIVATE ENEMIES:               Asc +    12th House  - Lord 12th
DEATH:              Asc +   8th House   - Moon
PERILOUS YEAR:      Asc +   Lord 8th    - Saturn
SUDDEN ADVANCEMENT:     Asc +   Sun  - Saturn

    In the event of an unknown birth time then use the following formula. Bring the SUN to the Ascendant and create an Equal House Chart using the degree of the sun, now look for the following: If sun were 3 Gemini new ascendent would be 3 Gemini.

    SUN TO ASCENDANT
MERCURY Position:   Point of Commerce
VENUS Position: Point of Love
MARS Position:  Point of Passion
JUPITER Position:   Point of Increase
SATURN Position:    Point of Fatality
URANUS Position:    Point of Catastrophe
NEPTUNE Position:   Point of Treachery
PLUTO Position: Point of Organization

Now bring the MOON to the Ascendant degree and the following is found:

    MOON TO ASCENDANT
SUN Position:       Point of Spirit
MERCURY Position:   Point of Faith
VENUS Position: Point of Female Children
JUPITER Position:   Point of Male Children

    As a point of reference, my Natal Point for Divorce is 18 Sagittarius.  When my progressed MOON conjuncted this point, I filed for a divorce.  I saw it coming and thought that I could prevent the event.  Needless to say, I was unable to correct and change the divorce.

    On my Natal Point for Marriage 20 Virgo, I saw my MOON progressing to this degree.  As I did not have a relationship at the time, I did not see the event of marriage.  When my progressed MOON hit that degree, I met a man and was married a short time later.

    My mother died when my progressed MOON hit my point for Death of a Parent.  So as you can see this little known point can have a major influence on our lives. I have a list of 177 lots if anyone is interested. I have done extensive work and research in this and the Blue Moons. Currently I have a research /
teaching article I have done.

About The Arabic Parts Pages

 Many of the formulas are duplicated under different subjects. Some of the subjects have multiple formulas. Some of the formulas with multiple subjects will be listed in multiple places under each individual term; others are listed with all the terms at one location.

 This list includes both modern and ancient parts. Please test both and see which you prefer for your delineations. I give credits for my sources, and they give credits for theirs. I hope later to index these a variety of ways -- by relevant house, by planets/points used in the formula, by formula, modern vs. ancient, who knows what else -- but I felt that this alphabetical list would be most helpful in just getting started.
