Oranges and Lemons Day is celebrated across London on the third Thursday in March, with the main festivities taking place at St. Clement Danes Church. The day commemorates the restoration of the church's bells, which play the tune of the nursery rhyme "Oranges and Lemons." Participants typically feast on oranges and lemons, sharing these citrus fruits with friends. The handing out of these fruits is rooted in an ancient custom, originally linked to the transport of citrus to Clare Market. The event has evolved over time, with children and church members playing the song on handbells. Despite historical challenges, including wartime destruction, Oranges and Lemons Day continues to be a vibrant celebration.
