Work out diwali date instantly with clear inputs, formula shown and shareable results.
Diwali falls on the new moon of the month of Kartika, which cannot be reduced to a simple formula, so the main day is taken from a published table and the five day festival is counted from two days earlier. Because the date depends on lunar observation and regional convention, published almanac dates rather than arithmetic are the reliable source.
