Move aside Super Tuesday, March 3 is National Anthem Day!
National Anthem Day commemorates the day the United States adopted “The Star Spangled Banner” as its National Anthem, according to NationalDayCalender.com.
"The Star Spangled Banner" was written by Francis Scott Key and became the National Anthem in 1931.
