If you look at the Federal calendar, you won't find a holiday called "Presidents Day". This is because according to section 6103(a) of title 5 of the U.S. code, the law which defines holidays for Federal workers, today is designated as "Washington's Birthday". But, wait a minute. George Washington was born on February 22nd, 1732, so why wouldn't we celebrate his birthday on February 22nd? We used to; however, Congress decided in 1968 that it would be a good idea to create several three-day Federal holidays for the convenience of workers. Along with Washington's birthday, Memorial Day and Veteran's Day were each officially moved to Mondays in 1971. Genius.
