Diwali, also written Deepavali, is the festival of lights celebrated across India and by Indian communities worldwide. It falls on the new moon (Amavasya) of the Hindu month of Kartik, which places it in late October or November each year. In 2026 the main day is Sunday 8 November, and the wider season runs across five days from Dhanteras on 6 November to Bhai Dooj on 11 November.
The night itself is marked by rows of clay diyas along doorways, windows and balconies, a Lakshmi Puja for prosperity in the evening, and an exchange of sweets and gifts between families, neighbours and colleagues. Homes are cleaned and repainted in the weeks before, accounts are balanced, and businesses open new ledgers on the first day of the new financial year.
Diwali means different things to different communities. For most of North India it marks Rama's return to Ayodhya after fourteen years of exile. In Gujarat it opens the new business year. In West Bengal the same week belongs to Kali Puja rather than Lakshmi Puja. In Maharashtra and Goa the day is celebrated as Narak Chaturdashi first, with an early oil bath. Tamil Nadu and Sri Lanka call it Deepavali and treat the ritual oil bath as the centre of the day.
What holds all of it together is light: the idea that a house lit up is a house that welcomes good fortune, and that the turn of the lunar year is a reasonable moment to settle debts, forgive grudges and start again.
