The US celebrates 'Veteran's Day' on November 11th, which coincides with Remembrance Day (or Armistice Day), though it's one of those holidays that are more of a footnote than anything else. Memorial Day apparently holds a much older heritage. According to Wikipedia:
[...] it originated after the American Civil War to commemorate
the fallen Union soldiers of the Civil War [...] By the 20th
century Memorial Day had been extended to honor all Americans
who have died in all wars.
