On the birthday of Krishna, Krishna Janmashtami numerous devotees flock to the ancient Krishna temple in old Patan Durbar Square to welcome Lord Krishna’s birth. Men and women chant "Narayan Narayan" and "Gopal Gopal".
This year’s Krishna Janmasthami was on September 1, 2010. As the Eastern lunar calendar is different from the Western solar calendar the exact date of such festivals can only be determined by astrological calculations.
