Answer:
The war officially ended in Europe on November 11, 1918. The day is commonly known as Armistice Day or Remembrance Day in many countries. It marks the signing of the armistice agreement between the Allies and Germany, which effectively ended the hostilities on the Western Front of World War I. The armistice went into effect at the 11th hour of the 11th day of the 11th month, and November 11th has since been recognized as the day of commemoration for the end of the war in Europe.
