Originally established in 1885 in recognition of President George Washington, the holiday became popularly known as Presidents' Day after it was moved as part of 1971’s Uniform Monday Holiday Act, an attempt to create more three-day weekends for the nation’s workers. While several states still have individual holidays honoring the birthdays of Washington, Abraham Lincoln and other figures, Presidents' Day is now popularly viewed as a day to celebrate all U.S. presidents, past and present.

While Washington’s Birthday on February 22 was an unofficial observance for most of the 1800s, it was not until the late 1870s that it became a federal holiday. Senator Stephen Wallace Dorsey of Arkansas was the first to propose the measure, and in 1879 President Rutherford B. Hayes signed it into law.

The shift from Washington’s Birthday to Presidents' Day began in the late 1960s, when Congress proposed a measure known as the Uniform Monday Holiday Act. Championed by Senator Robert McClory of Illinois, this law sought to shift the celebration of several federal holidays from specific dates to a series of predetermined Mondays.

Nevertheless, the main piece of the Uniform Monday Holiday Act passed in 1968 and officially took effect in 1971 following an executive order from President Richard M. Nixon. Washington’s Birthday was then shifted from the fixed date of February 22 to the third Monday of February. Columbus Day, Memorial Day and Veterans Day were also moved from their traditionally designated dates. (As a result of widespread criticism, in 1978 Veterans Day was returned to its original November 11 date.)
