A federal holiday to honor George Washington was established by Congress in 1880 on the date of his birth. Since that time, this day to honor one president has morphed into a day called Presidents Day to honor Washington, Lincoln and all presidents.

The original act of Congress, in 1880, proclaimed a federal holiday for government offices in the District of Columbia to honor George Washington on February 22. In 1885, this was amended to include all federal offices, so that is the year the whole country started observing Washington's Birthday.
The date of this observance was changed in the Uniform Holidays Bill, passed in 1968, and implemented in 1971. From then on, Washington's Birthday has been celebrated on the third Monday in February.
Before the Uniform Holidays Bill was passed in 1968, a draft was submitted to change the day from a day to honor George Washington to a day called Presidents Day to honor Washington and Abraham Lincoln. But, when the final version was passed, it only changed the date of the observance of Washington's Birthday from February 22nd to the third Monday in February.
The holiday has not been officially designated as anything other than Washington's Birthday, a day to honor the father of our country; however, in many states it is celebrated as Presidents Day.
Even though the holiday is still officially Washington's Birthday, all the states celebrate Presidents Day, but in different ways.
No matter where you live and whether you call the holiday Presidents Day or Washington's Birthday, the day is a day to remember the men who lead, and helped shape, our country.
George Washington was born on February 22, 1732 and died on December 14, 1799. He was the commander of the Continental Army in the Revolutionary War from 1775 to 1783. He presided over the convention which wrote the U.S.Constitution in Philadelphia, Pennsylvania and served as the first President of the United States from 1789-1797. At his funeral in 1799, Henry Lee claimed him to be "first in war, first in peace, and first in the hearts of his countrymen."
The Uniform Holidays Bill of 1968 was designed to have three-day weekends on Washington's Birthday, Memorial Day, Veterans Day, and Columbus Day. When a holiday falls on Saturday, it is observed on the Friday before, and when it falls on a Sunday, it is celebrated the following day.
The eleven federal holidays mentioned in the Uniform Holidays Bill are:
Presidents Day is celebrated throughout the United States on the third Monday in February, the same day as the federal holiday of Washington's Birthday. It honors the founding fathers of the U.S.
