The origin of Presidents’ Day lies in the 1880s, when the birthday of Washington—commander of the Continental Army during the American Revolution and the first president of the United States—was first celebrated as a federal holiday. In 1968 Congress passed the Uniform Monday Holiday Bill, which moved a number of federal holidays to Mondays. The change was designed to schedule certain holidays so that workers had a number of long weekends throughout the year, but it has been opposed by those who believe that those holidays should be celebrated on the dates they actually commemorate. During debate on the bill, it was proposed that Washington’s Birthday be renamed Presidents’ Day to honour the birthdays of both Washington (February 22) and Lincoln (February 12); although Lincoln’s birthday was celebrated in many states, it was never an official federal holiday. Following much discussion, Congress rejected the name change. After the bill went into effect in 1971, however, Presidents’ Day became the commonly accepted name, due in part to retailers’ use of that name to promote sales and the holiday’s proximity to Lincoln’s birthday. Presidents’ Day is usually marked by public ceremonies in Washington, D.C., and throughout the country.
