Washington's Birthday is a United States federal holiday (Government Holiday information) celebrated on the third Monday of February in honor of George Washington, the first President of the United States. It is also commonly known as Presidents Day (sometimes spelled Presidents' Day or President's Day). As Washington's Birthday or Presidents Day, it is also the official name of a concurrent state holiday celebrated on the same day in a number of states.
Titled Washington's Birthday, a federal holiday honoring George Washington was originally implemented by an Act of Congress in 1880 for government offices in the District of Columbia and expanded in 1885 to include all federal offices. As the first federal holiday to honor an American citizen, the holiday was celebrated on Washington's actual birthday, February 22. On January 1, 1971, the federal holiday was shifted to the third Monday in February by the Uniform Monday Holiday Act. This date places it between February 15 and 21, which makes the name "Washington's Birthday" in some sense a misnomer, since it never lands on Washington's actual birthday, February 22.
An early draft of the Uniform Monday Holiday Act would have renamed the holiday to "Presidents' Day" to honor the birthdays of both Washington and Lincoln, which would explain why the chosen date falls between the two, but this proposal failed in committee and the bill as voted on and signed into law on 28 June 1968, kept the name Washington's Birthday.
By the mid-1980s, with a push from advertisers, the term "Presidents' Day" began its public appearance. Although Lincoln's birthday, February 12, was never a federal holiday, approximately a dozen state governments have officially renamed their Washington's Birthday observances as "Presidents' Day", "Washington and Lincoln Day", or other such designations. However, "Presidents' Day" is not always an all-inclusive term.
There is a great article on Fox News that gives good reasons why we should celebrate Presidents' Day for something more than three days off or a trip to the mall. To read this article click on "Presidents Day: A Time to Remember the Greats".
