Victory in Europe Day, generally known as V-E Day, VE Day or simply V Day, was celebrated on 8 May 1945 to mark the formal acceptance by the Allies of World War II of Nazi Germany's unconditional surrender of its armed forces. The formal surrender of the German forces occupying the Channel Islands did not occur until the following day, 9 May 1945. It thus marked the end of World War II in Europe.
The term VE Day existed as early as September 1944,
in anticipation of victory. On 30 April 1945,  Adolf Hitler, the Nazi leader, committed suicide during the Battle of Berlin. Germany's surrender, therefore, was authorized by his successor, Reichspräsident Karl Dönitz. The administration headed by Dönitz was known as the Flensburg Government. The preliminary act of military surrender was signed on 7 May in Reims, France , and the final document was signed on 8 May in  Berlin, Germany.
The former Soviet Union, Serbia, Israel, and
Eastern Bloc countries have historically celebrated the end of World War II on 9 May. In Ukraine since 2015, 8 May is designated as a day of Remembrance and Reconciliation, but it is not a public holiday.

Upon the defeat of Germany, celebrations erupted throughout the western world. From
Moscow to Los Angeles, people celebrated.
United Kingdom, more than one million people celebrated in the streets to mark the end of the European part of the war. In London, crowds massed in Trafalgar Square and up the Mall to Buckingham Palace, where King George VI and Queen Elizabeth, accompanied by Prime Minister Winston Churchill, appeared on the balcony of the palace before the cheering crowds. Princess Elizabeth (the future Queen Elizabeth II) and her sister Princess Margaret were allowed to wander incognito among the crowds and take part in the celebrations. 
In the United States, the victory happened on President
Harry Truman's 61st birthday. He dedicated the victory to the memory of his predecessor,  Franklin D. Roosevelt, who had died of a cerebral hemorrhage less than a month earlier, on 12 April. Flags remained at  half-staff for the remainder of the 30-day mourning period.  Truman said of dedicating the victory to Roosevelt's memory and keeping the flags at half-staff that his only wish was "that Franklin D. Roosevelt had lived to witness this day".  Later that day, Truman said that the victory made it his most enjoyable birthday. 
Massive celebrations also took place in
Chicago, Los Angeles, Miami and especially in New York's Times Square.
Soviet Victory Day
The instrument of surrender stipulated that all hostilities had to stop at 23:01 (
CET), 8th of May, just an hour before midnight. Since it was already 9th of May in the European part of the USSR, most post-Soviet states, including Russia, as well as Israel commemorate Victory Day on 9 May instead of 8 May.
