Veterans Day is celebrated annually on Nov. 11 to honor those who have served in the U.S. armed forces.

The federal holiday dates back to WWI, when fighting between the Allied countries and Germany ended on the 11th hour of Nov. 11, 1918, according to the Department of Veterans Affairs. The date is generally regarded as the end of "the way to end all wars."

While Veterans Day always falls on Nov. 11, regardless of what day of the week the date is in a given year, the observance of the day is shifted if Nov. 11 is on a weekend.

In 2023, for example, Veterans Day fell on a Saturday, so many observations took place the day before on Friday. If the holiday falls on a Sunday, it is observed the following day on Monday.
