Although commonly known as Presidents Day, the holiday is still legally Washington's Birthday.
The holiday was shifted from Feb. 22 to the third Monday in February 1971 under the terms of the Uniform Monday Holiday Act of 1968. Because the holiday falls between Feb. 15 and 21 it can never fall on the actual anniversary of Washington's birth in 1732.
The term Presidents Day began being popularized in the 1980s, when retailers combined sales formerly held in conjunction with Washington and Abraham Lincoln's birthdays.
