On what date did the United States celebrate its 250th Independence Day in 2026?

The United States celebrated its 250th Independence Day on July 4, 2026.

The date follows the traditional national observance of Independence Day, which commemorates the public proclamation of the Declaration of Independence in 1776. The Second Continental Congress passed the Lee Resolution on July 2, but July 4 became the date printed on the Declaration and the date used for the national holiday.

The semiquincentennial marked 250 years from 1776 to 2026. Events took place before, during, and after July 4, including military celebrations, maritime gatherings, concerts, commemorative coins, and fireworks. The anniversary date itself remained July 4.

A common mix-up is to treat July 2 as Independence Day because Congress voted for independence then. July 2 was historically significant, but the holiday and the 250th-anniversary celebration are tied to July 4. The 2026 date also followed the 1976 bicentennial by exactly 50 years.
