Vaisakhi is the most important day in the Sikh calendar, commemorating the beginning of Sikhism as a collective faith.
London's Vaisakhi celebrations are an opportunity for people from all communities, faiths and backgrounds to experience a festival that is celebrated by over 126,000 Sikhs who live in the capital and 20 million people across the world.
All are welcome to attend the family-friendly event, which as well as music and performance, food and children's activities, will for the first time include films, talks and an exhibition.
This year's celebrations will also take place much closer to the official Vaisakhi festival - 14 April - than it has in previous years.
City Hall been working with representatives from the Sikh community, including Singh Sabha London East Gurdwara, EY Sikh Network and other groups, to create a culturally rich, enjoyable day that represents Sikh identity and culture.
The new location will enable a range of additional new activities to take place, such as film screenings, cultural talks and poetry readings, alongside a colourful outdoor programme of live performances.
Visitors will be able to enjoy traditional dance, turban tying and Sikh spiritual music (Shabad Kirtan). Food (langar) will be prepared and offered by volunteers from the Sikh community.
