Calculating Arabic Parts.

[Draco]

Hi all,

Just a quick question. Can you help?

When calculating arabic parts such as Pars Fortunae, the calculation is different depending on whether you were born during the day or the night.

I was born at 19:05, therefore during PM time so I presume I am to use the AS+Sun-Moon calculation.

However, at this time, although going dark, the Sun had not quite set, still being above the horizon. So should I use the AS+Moon-Sun formula?

In short what I am asking is this: Is the discrepancy between the use of the formula dependant upon whether you are born before or after noon (AM/PM) or whether the Sun is above or beneath the horizon (light or darkness)???

Some sources mention an 'AM/PM' formula, suggesting the discrepancy is about whether you're born before or after mid-day.

Some talk of a 'day and night' formula, suggesting that it is whether the Sun is above or below the earth that is important.

I am confused because the former would have me use one formula and the latter another.

I intuitively guess that the ancient arab astrologers would have made the consideration based upon whether it was light or dark as this is the immediately observable and symbolic phenomena.

I'm confused! :? Help?

Hi Draco


This doesn't answer your question, but I was reading on Skyscript.co.uk the other day and found these links:

to calculate the various parts:

www.noendpress.com/pvachier/arabicparts

and

www-personal.umich.edu/~pfa/dreamhouse/attic/lots/lotslist.html

for a list of the parts! (Sorry, I can't get that link to work properly. )

They probably not going to help much, but will proabably save a few brain cells somewhere along the line?

I don't know much about them, but they're fascinating.

Take care

Hi Hel,

Thanks for the link, but I am already using this calculator at the moment. :wink:

There is a similar calculator for midpoints too. They're really useful.

It's just I'm wondering whether the reversal of the formula depends upon whether you were born before or after midday (AM/PM), as some suggest, or whether it depends on whether you were born with the sun beneath the horizon (day or night) as some also suggest?

I was born PM, but with the Sun above the horizon, so I don't know which to use. :?

Is it neccesary to switch formula's at all?

There's no point in reversing the formula based on AM/PM, only on day/night.
AM/PM is a conventional setting, while day/night is a natural phenomena, it's universal. What matters is if the light of the Sun, the life-giver, is touching the earth or not. (clouds don't count......)

Some formulas have to be reversed by day/by night, some others not. Depends on if luminaries are involved, I guess. Couldn't say if there's a rule.

Hi Radu, and thanks for helping me clarify this.

I was born close to sunset, but not quite, as the world was still in daylight, so now I feel more confident having had some affirmation that the day formula (AS+Moon-Sun) is more appropriate. I felt this would make more sense. This makes my POF in conjunction with transitting Neptune, and I can feel this happening at the moment.

I just needed to clarify. It is just that talk of the 'AM/PM' formula rather than 'day/night' is a bit confusing, making me think that the '-Sun' formula is appropriate any time after midday. :?

So now I'll remember. Sun in house 1 - 6, subtract Sun, Sun in house 7 - 12 subtract Moon.

Cheers Radu.
