Remembrance Sunday - Wikipedia, the free encyclopedia:
"In the United Kingdom, Remembrance Sunday is the second Sunday of November, the Sunday nearest to 11 November (Remembrance Day), which is the anniversary of the end of the hostilities of the First World War at 11 a.m. in 1918.
In the United Kingdom, Remembrance Sunday is marked by ceremonies at local war memorials in most cities, towns and villages, attended by civic dignitaries, ex-servicemen and women (principally members of the Royal British Legion), members of local armed forces regular and reserve units (Royal Navy and Royal Naval Reserve, Royal Marines and Royal Marines Reserve, Army and Territorial Army, Royal Air Force and Royal Auxiliary Air Force), youth organisations (e.g. Scouts and Guides), and military cadet forces (Air cadets, Army cadets and Sea cadets). Wreaths of poppies are laid on the memorials and two-minutes' silence is held at 11 a.m."
