How should I calculate astrological chart by my hand even though planets move every moments.

[Rishes]

For calculate the chart by my hand, I should check planets' positions from ephemeris. But These Ephemeris Position is based on Midnight.

So Do I calculate chart at 14:00pm then Planets' positions would be moved into another degrees of zodiac especially Moon(because Moon is the best fastest planet)

Then How can I calculate the horoscope by hand?

And Horary Text book written by John Frawley tell us all ephemeris tables are based on everyday Noon. But astrodentist's ephemeris based on Midnight.

And John said in his book, we need to know how much time is gone from yesterday Noon based on GMT . Does it means if I calculate 4th May 2024years 14:30pm horoscope then I should add 12times ie 14:30 + 12hous = 16:30pm.

and also he states we should plus 4minutes per one degree of longitude of my location.

and How can I know longitude and latitude without Google search?

Rishes,

you do not have to worry about the continuous movement of the stars when calculating the positions in the birth chart that you draw up.

Be careful to differentiate between midnight and midnight (midnight of the following day)!

In the Astrodienst ephemeris, for the day of May 4, 2024, you have the position of the Moon:
- 4/5/2024 at 0h (UT): Moon = 17° 27' Pisces
- 5/5/2024 at 0h (UT): Moon = 2° 02' Aries
Calculation of the daily step of the Moon = 30° + 2° 02' - 17° 27' = 14° 35' = 14°.58.
Position of the Moon in the chart you want to draw up for 2:30 p.m.; I took 2:30 p.m. TU (2:5 p.m.) because you did not indicate the location):
let X be the ecliptic longitude to add to the position of the Moon on 4/5/24 at 0h UT:
X = (14h.5 x 14°, 58): 24h = 8°.8 = 8° 48'. Position of the Moon = 17° 27' Pisces + 8° 48' = 26° 15' Pisces.
Verification with the chart obtained with Astrodienst (more precise): Moon = 26° 14' 19" Pisces.

So other planets also can be calculated by above formula?

 

[Ecliptique]

yes, of course all the stars given in the ephemeris...
Be careful, you must obtain universal time (UT) from the time of birth. For example, for a birth in Seoul at 2:30 p.m., it would be necessary to subtract between 8:30 a.m. and 9:30 a.m. (depending on the date of birth and the application of summer time or not) from the time of birth, which would give a universal time between 5h and 6h to calculate the astral positions as I did.

Rishes,
There are many books available that guide one through the process of calculating the horoscope by hand. Though not terribly difficult, the process is a bit too complicated to post in a response or two on a forum like this.
There is a posting on this forum (under Recommendations I believe) with a long list of resources (books, websites, videos, etc) available. With all respect one would suggest taking advantage of those resources to answer the questions one may have about horoscope production and interpretation.
The horoscope itself is nothing more than a picture of the heavens relative to a specific time and place. Time, the terrestrial location of the native, and the positions of the planets are all defined in terms of coordinate systems. That is why the various calculations need to be understood and applied.
Best wishes for your continued study.

This is a lot harder than I thought, to find a simple on-line formula. The American Federation of Astrologers used to require novice astrologers to calculate a chart by hand, in order pass their qualifying exams. Now there just seems to be an assumption that, armed with your birth data, you just go to a computer and plug them in. Voila.

I found one AFA video, but the sound was so bad I couldn't listen to it. Basically you need your birth time, location, and date, plus an ephemeris (a good free one is on-line at Astrodienst, at www.astro.com . It is a noon ephemeris. Then you need a table of houses, which might be a booklet purchase, possibly through the AFA. But it looks like Astrodienst has free ones to download, with multiple house systems to choose from.

There is some trigonometry involved. The only formula I could find quickly was in this post by Shashikanta Nayak on a Quora thread:
https://www.quora.com/How-is-a-birt...ine-calculator-Where-do-I-learn-more-about-it
I've got some old books downstairs with the pre-computer era formula. If nobody else can find theirs, I can dig it out and get back to you.

gosh I did this every day for years!

If I recall right, I used log tables to calculate the Asc since we used equal house exclusively back then (being british trained). Having the Asc everything was divided equally. So after that I didnt need anything else, just plotted the circle and adjusted the calculations of the planets for time at position from gmt.

But calculating the individual differences one needs to remember you are dealing with a unit of 60. There are 60 units in every degree. So a subtraction needs to be mindful!! When you ‘borrow’ a unit, for subtraction, you are borrowing 60 not 1.

You need to always adjust for 60! Because half hour in unit of 60 is 30 but in the unit of 10(decimal) its 50. Etc etc.

There are many youtubes and instructions how to use a calculator to do this for you.

 

[FraterAC]

I never had to use any trigonometry at all. Just an ephemeris and table of houses. I used the table of proportional logarithms in the back of the ephemerides for a while, but pretty soon found my trusty $10 four-function calculator was quicker.
It took me 40 minutes to an hour to calculate and draw out a horoscope.
I drew a horoscope wheel (like the one below) and Xeroxed copies of it at work to use as a blank form and bought an accordion-type file to hold the paper charts and calculation sheets and I was off.
I followed the instructions in Simplified Scientific Astrology meticulously, step by step, every time. Probably why I can't remember all the details today -- I never memorized them.
Everything was tropical and Placidus.
As soon as I could afford a PC (they were at least $10-15,000 in 2024 dollars) one of the first things I put on it was an astrology program -- Halloran's AstroDeluxe.

 

[FraterAC]

In addition to Simplified Scientific Astrology by Max Heindel, Alan Oken's Complete Astrology also has good comprehensible instructions for calculating charts by hand. Both are still available. An ephemeris and table of houses are still very useful tools to have handy.
That said, I'm no masochist (that's the cue for somebody here to post links in color and large type to definitions of "masochist"). I say, if the computer can do it, make the computer do it.

 

[waybread]

Actually, FraterAC, maybe you don't want the Merriam-Webster dictionary definition:
a person who derives sexual gratification from being subjected to physical pain or humiliation : although other on-line dictionaries often leave out the sexual part.

Long ago and far away, I recall a professor in a field that was described as both an art and a science, saying, "There is absolutely no benefit in doing things the hard way."

But a really good Australian astrologer, Alice Portman once noted that when she taught astrology back in the old days, students had to learn to construct charts by hand. The first point to come up is the MC. Which maybe says something a bit more profound.

 

[FraterAC]

WB,
As I said

I'm no masochist

Pain and frustration does not give me any kind of jollies.
That's why I've shelled out the $ for four different programs (I had some other DOS-based software on another machine years ago that did lunar tide cycles, it went under with that old machine). If there was some kind of computing device Ptolemy could have used (I'm opining there probably was -- cue large-print link to Antikythera mechanism) I'm sure he'd have used it.
It's not just laziness and impatience. It's also trying to eliminate (my) human error.

 

[waybread]

Oh, I wouldn't have thought otherwise, Frater. That Meriam-Webster definition took me aback.

I imagine Ptolemy had a couple of well-trained apprentices to do his calculations for him. Just a hunch.
