Presidents Day is observed on the third Monday of February.

Although many feel Presidents Day is a time to honor all former U.S. presidents, the federal holiday is actually the official observance of George Washington's birthday - Feb. 22, 1732.

To commemorate Presidents Day, the Census Bureau pulled information from its geographic database on the country's 100 most common place names, either the exact name or part of a longer name, such as "Fort Washington" or "Lincoln Park."

1. Washington
3. Lincoln   
4. Jackson
6. Jefferson
7. Clinton
9. Madison
10. Monroe
13. Grant
24. Harrison
26. Adams
47. Cleveland
49. Garfield
56. Wilson
65. Taylor

Also worth noting:

Although never a president, founding father Benjamin Franklin's last name was the second most common name of a place.

Mount Vernon, George Washington's home in Virginia, is tied for 110th place, with 18 places.
