About Diwali Date Calculator

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.

Formula

Festival span

the five day festival runs from Dhanteras, about two days before Lakshmi Puja, to Bhai Dooj two days after

Assumptions and limits

  • The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
