2. What Diwali is

Diwali (Deepavali), “the row of lamps”, is the festival of light. It celebrates the return of Rama to Ayodhya and is above all the night of Lakshmi Puja, when homes are cleaned and lit with diyas and Lakshmi, the goddess of prosperity, is worshipped with Ganesha in the evening. It falls on the Amavasya (new moon) that ends the month of Ashvin in the amanta calendar, called Kartika Amavasya in the purnimanta calendar of North India.

3. Why Diwali is a day earlier in the UK, USA and Canada

The Lakshmi puja is done in pradosh, the three muhurtas after sunset, on the evening the Amavasya holds then. In 2027 the Amavasya begins at 16:19 BST on Thursday 28 October, before sunset in London, and at 11:19 in New York and Toronto. So the UK, USA and Canada keep Diwali on Thursday 28 October. In India it begins at 20:49 IST, after that evening’s pradosh; the next evening the Amavasya still holds at sunset (it ends at 19:07 IST), so India keeps Diwali on Friday 29 October.

Many UK and North American families follow an Indian calendar and would celebrate on the 29th. Both dates are kept in good faith; this page gives the date calculated for your own city.

4. The five days of Diwali 2027

Dhanteras opens the festival and Bhai Dooj closes it. Dhanteras is on 26 October in North America but 27 October in the UK and India. In the UK, USA and Canada, Choti Diwali (with its bath before sunrise) and the Lakshmi Puja (in the evening) fall on the same day, 28 October.
