I think it's really good and admirable that you want to learn how to calculate charts, not just type the data into online websites. Once you've learned to calculate them yourself it's more accurate to use a computer-calculated chart for the reasons above, but it's really a very good idea to first d...

Re: Sidreal Time (ST) Conversion Question I will assume that the GMT of your birth is indeed 15:23 as you say, which means that you were born at 10:23 a.m. EST. You must convert 15:23 to sidereal time or "accelerate", multiplying by 1.002738 or adding 10s for each hour, the result is 15:25:32. To this you must add the ST at 0h in...

With that ST you look into a Table of Houses, which should give the Asc. in 17,29 Virgo and the MC in 15,55 Gem. Juan The Table of Houses that I have in the back of the book, even based on my calculations does not give anything but a rounded version of the degrees, i.e. my calculation of 4:56:51 ST...

After having slept on it, this is the only thing that is stumping me.

Can you give an example of that? Also where did you find the midnight ephemeris and why use that one instead of a regular ephemeris? And how did you get the Greenwich GST at moment of birth? I have the updated American edition of Parkers' (2001) and what I'm learning from you is easier and simpler t...

Juan wrote: (seconds/60+minutes)/60+hours = decimal hours. J. Awesome. Thanks! Now how would you convert decimal to time? I'm learning so much already and taking LOTS of notes.

Thanks Juan. I'm still trying to figure out how to enter the time into the calculator to get the results that you are getting. Any suggestions? ETA: I'm really trying not to be a bother, I'm just trying to get the basics so I can do well and do it correctly.

And another update that I just found out. I was born at 10:23 PM not AM. Off to do more corrections, LOL! Forum: Nativities & General Astrology Topic: Sidreal Time (ST) Conversion Question Replies: 17 Views: 10382 Thu Jun 16, 2011 2:11 am Jump to post

Thanks, Juan. Okay, I guess it's back to square one. :) One question though what's a sexagesimal? Math was my favorite subject in high school and I've forgotten most of it. And I was really surprised to see how much math was involved in Astrology. And how do you put in something like ST = 16h56m53s ...

Okay, so I was typing up a reply and hit a button then it was erased. Darn! Thanks, Juan. I have some questions for you. How do you multiply a decimal and time and then convert back to a decimal? Also, when you accelereated the time, did you add the seconds or multiply by 1.002738? When you subtract...

Sidreal Time (ST) Conversion Question Okay, so now I'm pulling out my hair already, LOL! As noted in my other post, I'm using Parkers' Astrology to start out my studies in Astrology. However, I'm stumped! For those of you who may have the book, I'm on page 99. My birthdate is Jan. 5, 1987, and the longitute and latitude of my birthplace...
