the birth date, find the interval between the GMT time and noon of that day, not
the actual birthday.)
For our examples:
8AM-GMT
count ahead to noon
=4 hours
8PM-GMT
count back to noon
= 8 hours
lAM-GMT
count ahead to noon
= 11 hours
IPM-GMT
count back to noon
= 1 hour
We have obtained the Sidereal Time (ST)at the Prime Meridian at noon on
the date of birth. The next step is to discover the Sidereal Time at Greenwich at the
timeofbirth on thedate ofbirth. In order to do this we must employ the interval time
just determined, adding to or subtracting from our Sidereal Time (In our example:
17h 38m 23s), for AM-subtract, for PM-add. (Remember that if your calculations
have lead you into the days before or after the birth date, use the Sidereal
Time at noon on that day and not that of the actual day of birth.F?
For our four examples:
ST at Greenwich for
noon on birthday =
1711 38m 23sAM
-4hrs=
13h38m23s
STat Greenwich for
noon on birthday =
1711 38m23sPM
+8hrs=
25h 38m 23s
STat Greenwich for
noon on birthday =
1711 38m23sAM
-l1hrs=
6h38m23s
STat Greenwich for
noon on birthday =
1711 38m23s PM
+lhr=
18h 38m 23s
We must now make an adjustment to allow for the difference between
Sidereal and regular time. This is called the Acceleration on the Interval. This is
accomplished by adding or subtracting ten seconds for everyhour and one second
for every six minutes of interval time, always following the rule of subtracting for
AM, adding for PM.
For our examples:
AM: subtract PM: add AM: subtract PM: add
interval = 4 hrs. interval = 8 hrs. interval = 11hrs interval = 1 hr.
Accel onInter.= 40s. Accel onInter. = 80s. Accel on Inter. = 110s. Accel on Inter.= lOs.

This tells us the Sidereal Time at thePrime Meridian for thetimeofbirth. Next
we must convert this to determine the Sidereal Time for the time of birth at the
place of birth. The difference in time depends on the distance between Greenwich
and the place of birth. This is known as the Longitude Equivalent in Time. To arrive at
that figure we multiply the birthplace longitude by 4, naming the resulting numbers
hours, minutes, and seconds; thus converting longitude distance into time:
70 Ifyour calculations ever leave you with a negative (minus) number for the ST at Greenwich, add
24 hours.
