Diwali date estimator
Enter a year to find the date of Diwali — specifically Lakshmi Puja, the main night, which falls on the new-moon day (Amavasya) of the Hindu month of Kartik. The tool shows the date and weekday for that year.
Because Diwali tracks the true astronomical new moon there is no simple arithmetic formula, so this tool uses curated published panchang dates. It is privacy-first: the lookup runs entirely in your browser and nothing is sent anywhere.
