What's the difference between Memorial Day and Veterans Day?

Memorial Day cemetery flags
A solider from the 3rd U.S. Infantry Regiment, "The Old Guard," placed flags at grave sites during the "Flags-In" ceremony at Arlington National Cemetery in Arlington, Va., on May 22, 2014. A small U.S. flag was placed 1 foot in front of more than 220,000 graves in the cemetery to mark Memorial Day.
