Diwali On The Square returns to Trafalgar Square on October 25

London Mayor Sadiq Khan has announced that Diwali On The Square will return to Trafalgar Square on Sunday, 25 October 2026, with a free celebration from 1 pm to 7 pm. The day opens with 200 dancers performing in the centre of the square, followed by a main stage of music, dance and performances by London's Hindu, Sikh and Jain communities. The event comes two weeks before Diwali itself, which falls on 8 November 2026.

Diwali On The Square is a major public Diwali celebration held in the square that sits at the symbolic centre of London. Its return each year reflects the size and visibility of London's Indian-origin communities, and the way Diwali has become part of the city's public calendar alongside other festivals.

The programme shows how the festival is presented to a wide audience. Diwali, the festival of lights, marks the victory of light over darkness and, according to tradition, the return of Lord Rama to Ayodhya after his exile, which is why a Ramayana puppet show is part of the day. It is celebrated by Hindus, Sikhs and Jains, each with their own traditions: for Sikhs, the same period marks Bandi Chhor Divas, and for Jains, it is linked to the nirvana of Lord Mahavira. By naming all three communities, the organisers make clear that the event is meant to reflect that variety rather than a single tradition.

For Indian readers, the event is a measure of how Indian culture travels and adapts. Activities such as sari and turban tying, yoga and meditation are practical ways of introducing the traditions to Londoners of every background, while vegetarian food reflects the festival's customs. Because the event is held on a Sunday two weeks before Diwali, it also allows families to take part without clashing with their own celebrations at home and in temples on the day itself.

Short-term: Large crowds are likely in central London on 25 October, with 200 dancers, stage performers and food stalls taking part; visitors should allow for bag searches and capacity limits at the entrance.

Long-term: Annual events like this keep Diwali in the public life of London and help younger generations of the diaspora stay connected to their heritage, while introducing the festival to people of other faiths.

Who is affected: London's Hindu, Sikh and Jain communities, visitors to central London, local artists and food businesses, and families of Indian origin in the UK.
