Remembrance Sunday, observed on the second Sunday of November in the United Kingdom, is a day dedicated to honoring British service members who lost their lives in wars and military conflicts since the onset of World War I.

Aligned with the proximity of November 11, which is Armistice Day commemorating the cessation of World War I hostilities in 1918, Remembrance Sunday involves solemn ceremonies led by the King. These events include memorials and the laying of poppy wreaths at the Cenotaph in London.
