Dear Gurudeva Maharaj:

Pamho. AgtSP!

Thanks for hanging in there with me on this important topic!  The simpliest explanation I can come up with is that Gaura Purinama is always the last full moon of the  seasonal (tropical) year which ends BEFORE  the first day of Spring (Vernal Equinox) or BEFORE March 20th  (3/20) of the new calendar year;  the new devotional year begins the day after THIS FULL MOON.

The next projected date for Gaura Purnima as per the calendar produced by Iskcon GBC for the end of this year 526 is Mar 27th, 2013,  which is 7 days PAST  the Vernal Equinox (3/20). THIS IS THE PROBLEM IN A NUTSHELL: One third of the dates we have been celebrating as the Lord's birthday (GP) have been AFTER the Spring equinox. This is a clear No No. The correct date  for Gaura Purnima 526 should be Feb 26th 2013.

I really hope this helps helps clarify the problem and the need for change.

Your Humble Servant, Saranga Thakura

Haribolo!

HpS - AGTSP   pamho.   The general idea is a little more clear.   Seems that we are talking about the differences that result from the contrasts with the luna calendar and the solar calendar, no?    For this there is an extra month every few years to put the two in sync.

Have you discussed this with any ISKCON astrologers?   One nice one is Srikara Das [email protected]
