National Virginia Day is observed worldwide every September 14 to recognize Virginia as the tenth state to ratify the U.S. Constitution and formally join the Union. This day celebrates Virginia's rich history, including its status as the first permanent English colony in North America and its nickname, the Old Dominion. The state is notable for being the birthplace of eight U.S. presidents, including George Washington and Thomas Jefferson. Virginia's history also includes significant events leading up to the American Revolutionary War, such as the colony's coordination with other colonies through the Committee of Correspondence and its early ratification of the Articles of Confederation. The observance of National Virginia Day was initiated by the National Day Calendar as part of its National State Days project, which honors each state in the order they joined the Union.
