The 4th of July falls on a Saturday this year, but many government offices will be closed tomorrow (7/3) in observance of the holiday. Most Post Offices will close at noon, and the Washington County Mini Bus will not be running. The 4th of July has been celebrated since 1776. It commemorates the first Continental Congress adopting the Declaration of Independence. Although the signing of the Declaration was not completed until August, the 4th of July holiday has been accepted as the official anniversary of U.S. independence and is celebrated in all states and territories of the U.S.
