Someone called me and said karwa chauth. dot com says "This year Karwa Chauth is on 25th October and your own mypanchang.com says 26th. What's the truth? Like anyone will say I am right! I am right! hence i said I am right but i don't like to say that without explanation. I've no clue why some sites say 25th October 2010. When I was visiting Vancouver BC last week. Mr. Ganesh Nanda from Nanda Jewellers also raised the same point, saying some people says 25th and some say 26th October. Which is true please punditji explain us.
Rule for karwa chauth:
Most people believe that it's a 4th night after purnima. Actually its not the 4th night from purnima but the 4th tithi after purnima which is chaturthi tithi prevailing during the moonrise.
More detailed rule as per dharmashastra.
Tithi Chaturthi must prevail during moonrise if not take the second day. It's not the 4th day after purnima but chaturthi tithi visible during moonrise. That's the important rule.
On the moonrise time of the 25th October chaturthi is visible only in the one place in the whole world is -- Hawaii, rest of the world tritiya is visible at the moonrise of 25th october. Hence 25th cannot be taken for karwa chauth. When chaturthi isn't visible during the moonrise of both days then we need to take the second day. Hence we have to take 26th October for karwa chauth for the rest of the world. If you are reading this please change your website to reflect the correct date.
