All auspicious events in the Hindu world take place according to the Panchangam, or the Astrological Hindu Calendar. Hindu Astrology is a precise science, taking into account the latitude and the longitude of location into the calculations. For this reason, the timing of various events varies based on location. The calendar, to be complete, should list the rising and setting time of the various stars and planets, and also the beginning and end of the various “kalams” or time periods. I have had trouble obtaining a panchangam for the location I live in, which is not in India. For me, there is no essential need for the calendar, and yet, some of my readers (there seem to be none so far!) might be looking for one. I found two such calendars or panchangams on the web today.
The first calendar, the mudgala panchangam has the following features:
The next, which seems to cover a lot of geographical locations, including various cities in Europe, North America and Australia is the Vedic Calendar provided by the Himalayan Academy. There are panchangas available for a few years here, with archived panchangas from the past too. I like this much better, but it is up to you to take a pick.
