London is once again set to shimmer and sparkle as the city embraces Diwali, the Hindu festival of lights. Celebrated this year on Monday, October 20, 2025, Diwali signifies the triumph of light over darkness, good over evil, and knowledge over ignorance. The capital is alive with a diverse array of events, from grand public gatherings to intimate restaurant experiences, offering Londoners and visitors alike a chance to partake in this joyous occasion.
Diwali, also known as Deepavali, is a significant festival for Hindu, Sikh, Jain, and Buddhist communities worldwide. Its observance spans five days, each with its own meaning, and is marked by the lighting of diyas (oil lamps), colourful rangoli designs, gift exchanges, and lavish feasts. This year, the festivities are particularly vibrant, with a packed schedule of events leading up to and following the main celebration.
Major Public Celebrations: Trafalgar Square and Beyond
Central London will once again be the epicentre of large-scale Diwali celebrations with the annual Diwali on the Square event at Trafalgar Square. Organised by the Mayor of London, this free, open-to-all festival typically draws tens of thousands of attendees. For 2025, the event took place on Sunday, October 12, transforming the iconic square into a hub of cultural expression. The day was filled with a colourful opening dance sequence by hundreds of performers, a main stage showcasing music and dance from London’s Hindu, Sikh, and Jain communities, and family-friendly activities like sari and turban tying, yoga, and puppet shows.
