If we divide this number by 7 the remainder would be 5. As Kaliyuga
commenced with Friday, the period of time above defined closed with
Tuesday, as according to Suryasiddhanta a weekday is counted from
midnight to midnight.
It is to be noticed that in places where Barhaspatyamanam is in use
Krishnapaksham (or the fortnight of waning moon) commences first and is
followed by Suklapaksham (period of waxing moon).
Consequently, the next day after the 15th day of the waxing moon of
Aswina will be the 1st day of the waning moon of Kartika to those who
are guided by the Barhaspatyamanam calendar. And therefore the latter
date, which is the date mentioned in the inscription, was Wednesday in
the year 4362 of Kaliyuga.
The geocentric longitude of the sun at the time of his meridian passage
on the said date being 174 deg. 20' 16" and the moon's longitude being
70 deg 51' 42" (according to Suryasiddhanta) it can be easily seen that
at Gaya there was Padyamitithi (first day of waning moon) for nearly 7
ghadias and 50 vighadias from the time of sunrise.
