Diwali 2025 date: October 20 or 21? Here’s when to celebrate the festival of lights

Diwali’s celebration date in 2025 is split between October 20 and 21 due to the lunar calendar’s Amavasya period spanning two days and varying sunset times. Cities with sunsets after 5:30 pm may celebrate on October 20, while those with earlier sunsets might observe it on October 21. Lakshmi Puja is scheduled for October 20, with local timings varying.
