March 0
March 0 is an imaginary date. This formulation may be used in software such as Microsoft Excel to refer to the last day of February as a way of allowing for the fact that the number of days in February varies in leap years.[1] It can also be used as a term for half-birthdays of people born on August 29, 30 and 31.
"March 0" is sometimes used by astronomers as a synonym for the last day of February.[2]
