Today is Veterans Day, the day when patriotic Americans honor those who have served in our military. At various times and in various places the date also has been called Armistice Day or Remembrance Day.
It happens on 11/11 because it was on that date in 1918 that the "Great War" we later learned to call World War I ended, at eleven o'clock in the morning. If you enjoy being an American, thank the vets you know for preserving it.
