On Sunday, we observe Veterans Day, an official United States holiday which honors men and women who have served in our armed forces.

A lot of people get Veterans Day and Memorial Day mixed up, so here's something to help you remember the difference between the two- Memorial Day is for remembering those who died in military service.  Veterans Day is to honor all veterans, both living and deceased whether they served in wartime or in peacetime.
