It is realized that many of you have access to discs which contain the following information, thereby eliminating the need to do the math in an Astrological chart. However, it is recommended that all interested in this subject learn how to calculate the elements of a chart without relying on high-tech solutions. All that is required is a standard 4-function calculator, and preferably one with a 12 digit read out. The only difficulty one may have is getting used to do math on the calculator and converting all minutes and seconds of time and arc into decimals. Yet , all the decimal determining is done on the calculator,and does not require writing out anything, except for the answers to the math. For an example chart, I shall demonstrate a birth on Nov. 11th, 1971, at 15:30 MST, in Tucson, Ariz.
The first thing to do is to find the co-ordiantes of Tucson, which are 110W58.1 (longitude) x 32N13 (latutude). Immediately find the LMT difference to UT. Your answer should be -07:23:52. Now begin the calculations;
MST...............................................15:30:00
diff to UT.....................................+07:00:00
UT.................................................22:30:00 (= 22.500 hrs)
RA incr ..........................................00:03:42
Sidereal Time for 11/11/71...........03:17:57 (MS/n = 03:21:39)
Greenwich RAMC...........................25:50:99 (un-reduced)
LMT diff........................................-07:23:52
RAMC of birth place......................18:27:47
Remember, when adding or subtracting time, the columns contain units of 60s'. For a more complicated example of borrowing time columns, lets say that we have come up against such a problem as this:
Greenwich RAMC..........................03:12:14 (26:71:74)
LMT diff.......................................-07:23:52
RAMC.......................................... .l9:48:22
It is necessary, in our example, to built up the 03:12:14 to a value that can be subtracted from by the value of LMT. To increase the hours column, borrow 24 hours from the RA circle. This make the 03 into 27 hrs. Next borrow from the 27 hours one hours worth of minutes (60) and add that to the minutes column which make the 12 into 72. And finally borrow one minutes worth of seconds (60) from the minutes column and add that to the 14, therefore,we arrive at 26:71:74.
If you have a calculator that can add and subtract time, these types of calculations can be facilitated. However, using a standard 4-function unit is just as valuable by placing a "0" between the hour, minutes, and seconds. It may take a little getting use to, but once you have become accustomed to calculating time in this manner it is really quick and simple.
There will be math requirements when the given time or arc contains hours, minutes and seconds to be converted into decimals. For example, lets say that a value as l7:54:34 needs to be converted into hours and decimal. First divide the 34 seconds by 60 = 0.5666, then add the 54 minutes, and divide that by 60= 0.909444 then adde the 17 hours= l7.909444 hours.
