Diwali 2026: Mark your calendars for India's festival of lights

Diwali 2026 will be celebrated on October 29, bringing clarity to those uncertain whether the festival falls in October or November this year. The date marks the new moon day, or Amavasya, in the Hindu month of Kartik, which determines when Hindus, Sikhs, Jains, and Buddhists across India and the diaspora light diyas and exchange sweets.

The five-day Diwali festival season begins with Dhanteras on October 27, followed by Choti Diwali on October 28. The main celebration on October 29 will be followed by Govardhan Puja on October 30 and Bhai Dooj on October 31, completing the traditional festival cycle.

Diwali's date shifts annually between late October and early November, as the Hindu lunar calendar does not align with the Gregorian calendar. This year's October 29 date allows families and businesses ample time to plan celebrations, procure goods, and prepare their homes for the festival season.

The festival, celebrated with fireworks, rangoli designs, and family gatherings, holds deep cultural and religious significance across India. Businesses typically declare the Diwali week a festive holiday period, with many Indians returning to their hometowns to celebrate with loved ones.
