Celebrate Diwali on 12th November, 2004

Diwali comes every year on the day (night) of New Moon (Amavasya) in the month Kartik (according to Hindu calendar, and approximately around Oct.-Nov) following the autumnal equinox. Diwali date (according to Hindu calendar) therefore does not fluctuate and is a one day affair, even though people in various parts of India may celebrate it differently (e.g. over several days).
