Yes, the United States uses the Gregorian calendar. The switch from the Julian to the Gregorian calendar actually happened before the United States was a country. Great Britain and its American colonies changed from the Julian to the Gregorian calendar by dropping the 11 days between September 2 and September 14, 1752.
