February 31
This article is about February 30 and 31 as non-existent dates. For legitimate use of February 30 in calendar systems, see February 30.
February 30 and February 31, with regard to the modern Western (revised Gregorian) calendar, are imaginary dates that are used for example purposes, to make it clear regardless of context that the information being presented is an artificial example and not real data. In this respect, these "dates" are similar to other clearly fictional data used for similar purposes, such as "John Q. Public", "Jane Doe", "Anytown, USA", "(123) 555-1234", "123 No Such Street", etc.
