Victory in Europe Day, generally known as VE Day (United Kingdom) or V-E Day (US), is a day celebrating the formal acceptance by the Allies of World War II of Nazi Germany's unconditional surrender of its armed forces on Tuesday, 8 May 1945, marking the end of World War II in Europe. VE Day is celebrated across Western European states on 8 May, with several countries observing public holidays on the day each year, variously called Victory Over Fascism Day, Liberation Day or simply Victory Day.

​

Russia, Belarus, and Serbia celebrate on 9 May, as do several former Soviet bloc countries. Israel also marks VE Day on 9 May, as a result of the large number of immigrants from the former Soviet bloc, although it is not a public holiday. The term VE Day existed as early as September 1944, in anticipation of victory.
