Remembrance Sunday is observed in the United Kingdom every second Sunday of November to commemorate servicemen and women who served in World War I, World War II, and later conflicts. Established after World War I, it has evolved from being solely recognized on Armistice Day to a separate observance since World War II, with ceremonies now held on both days. The national ceremony takes place at the Cenotaph on Whitehall in London, where government officials, ex-servicemen and servicewomen, military cadets, and youth organizations gather. Attendees typically wear remembrance poppies, a symbol inspired by the poem "In Flanders Fields" by John McCrae, to honor those who lost their lives in conflict. The ceremonies begin at 11 a.m. and include the laying of wreaths and a two-minute silence, with the first wreath laid by the Queen followed by other members of the Royal Family.
