In the United States today is the federal holiday officially known as George Washington's Birthday. President Washington's birthday is actually February 22 but the celebration was shifted to the third Monday of February by the 1971 Uniform Monday Holiday Act. In the mid-1980's advertisers started calling the day President's Day, also recognizing President Lincoln's birthday (which some states already did although it was never a federal holiday) on February 12, and the name seems to have stuck. As such about a dozen states have officially renamed their holiday Presidents Day to honor both Washington and Lincoln.
Just a little history lesson with your coffee this morning.
