Armistice Day

https://en.wikipedia.org/wiki/Armistice_Day

Armistice Day (which coincides with Remembrance Day and Veterans Day, public holidays) is commemorated every year on 11 November to mark the armistice signed between the Allies of World War I and Germany at Compiègne, France, for the cessation of hostilities on the Western Front of World War I, which took effect at eleven o'clock in the morning—the "eleventh hour of the eleventh day of the eleventh month" of 1918. While this official date to mark the end of the war reflects the ceasefire on the Western Front, hostilities continued in other regions, especially across the former Russian Empire and in parts of the old Ottoman Empire.

The date was declared a national holiday in many allied nations, to commemorate those members of the armed forces who were killed during war. An exception is Italy, where the end of the war is commemorated on 4 November, the day of the Armistice of Villa Giusti. In the Netherlands, Denmark and Norway World War I is not commemorated as the three countries all remained neutral.

The first Armistice Day was held at Buckingham Palace, commencing with King George V hosting a "Banquet in Honour of The President of the French Republic"^[1] during the evening hours of 10 November 1919. The first official Armistice Day events were subsequently held in the grounds of Buckingham Palace on the morning of 11 November 1919. This would set the trend for a day of Remembrance for decades to come.

Most countries changed the name of the holiday just prior to or after World War II, to honor veterans of that and subsequent conflicts. Most member states of the Commonwealth of Nations, like United Kingdom and (as Canada in 1931), adopted the nameRemembrance Day, while the United States chose All Veterans Day (later shortened to 'Veterans Day') to explicitly honor military veterans, including those participating in other conflicts. "Armistice Day" remains the name of the holiday in France and Belgium, and it has been a statutory holiday in Serbia since 2012. In New Zealand and Australia observance ceremonies take place, but the day is not a public holiday.
