The original time of birth is not really reliable. I do not have a time on the birth certificate and only when I was interested in having my chart done 18 years after my birth did I ask my mother. My sister's time was recorded and I noticed was 4.15 and that is too much coincidence. My brother remembers I was born in the afternoon, that is as close as it gets I think.
I can relate to this; I went six months studying astrology with the wrong birth time since my mother had told me I was born at 3:44 AM--the time recorded on my brother's birth certificate.
To give parents credit, I imagine it's difficult to keep the times of birth of various children straight in one's head--and of course, the mother had more important things on her mind at that moment.
Calculation is not my strongest point. AAARGHH!
My brain is turning to mush trying to follow it all!
I'm fairly decent at math, but these kinds of calculations are confusing because there is so much to keep track of--not to mention that the numbers rarely work out evenly.
At 15.41 the Moon is 1o21 from the DC (one and a third degrees approx), which converts to 1.33 for a decimal calculator.
Yes, this is correct.
If you divide 1.33 by 13 on the calculator you get 0.1 (so then is that 0.1 of a 24 hour day?) and 24 x 0.1 = 2.4
Is that how you get the 2 hours 35 minutes approx?
This gives a fraction of 4/39, but if you have a decimal calculator, it works out to 0.102564102--approximately 0.1 like you said.
Unfortunately, I've made so many calculations that I cannot find the one you are referring to, but I generally created an equation using x and then solved for the variable.
Generally, you have to determine the next unit of time that makes sense in your calculation, asking yourself, "What exactly is this a fraction of?" In the previous example, 4/39 is a fraction of a day, which is divided into 24 hours.
So first, I would have set up the equation 4/39. Therefore, I created the equation 4/39 = x/24, cross multiplied to receive 96 = 39x, and divided both sides by 39 to receive 2 6/13, or 2.461538462 using decimals.
So then we would have 2 6/13 hours. Hours are divided into sixty minutes, so I would drop the two and use the fraction 6/13 to set up another similar equation--6/13 = x/24. Again, I cross-multiplied to receive 13x = 144 and divided both sides by 13 to receive 11 1/13, or 11.07692308 using decimals.
So far, we have 2 hours and 11 minutes; now we want to determine the seconds.
Again, we drop the 11 and keep the fraction 1/13, setting up another equation; 1/13 = x/60. You cross-multiply again to receive 13x = 60 and divide both sides by thirteen to receive 4 8/13. Since the calculation program doesn't allow any units smaller than seconds, I simply rounded up to the nearest second.
Unfortunately, these numbers aren't matching up exactly with yours because I've been using a different calculator and only rounded at the end.
Part of the problem might also be that I calculated that there was a distance of 1 2/5 or 1.4 between the Moon and the Descendant; this number divided by thirteen gave me 7/65 or 0.107692307 to start my series of calculations. I can go over the exact numbers and calculations I used if it would be helpful.
After this I get completely lost. What do are you subtracting 2 hours and 35 minutes from?
Edit -
Wait, do you take away 2 hours 35 minutes from 15 December which is the 273 day? Then you would get late on 14 December 9.25pm, I think I got it.
It puts the Moon in Gemini which is good.
You've got it!
I did one general calculation using midnight for the day you were born and another with the given time of birth, which alters the result by a few hours.
Now I have to gather my thoughts again for working out the next bit about the conception ascendant and how it relates to natal AC, I am not quite there with you yet because if you put the DC at 24 degrees in the natal chart the Moon is no longer below the horizon and the rules change that were used to make the calculation in the first place.
The main idea to remember is that the position of your natal Moon is the position of the Descendant in the Epoch chart, and the position of your natal Descendant is the position of the Moon in the Epoch chart. Since the Moon generally changes degrees and signs more slowly than the Descendant, I usually first calculate a chart in which the Descendant is at the same degree as the natal Moon and then look at the position of the Epoch Moon to determine the degree of the Descendant.
You don't have to worry about the Moon not being in the same position it was in your natal chart as long as the Moon equals the degree of your natal Descendant and the Descendant equals the degree of your natal Moon.
What is the calculation to get the time of 1.15pm on 15 December?
We divided 9 1/13 by 13 and subtracted this number from 273 days to receive 272 days 11/39, which corresponds to approximately 264 days, 6 hours, 46 minutes, and 9 seconds before you date of birth. I then used the date calculator to subtract this number from your date of birth--not from your exact date and time of birth.
This yielded a result of Wednesday, December 23, 1959 at 5: 13 :51 PM
This was still using the old birth time in which the Moon was about 9 1/13 away from the Descendant, though, which didn't yield a good result.
