On days when the federal government isn't doing business, neither is the post office. The U.S. Postal Service follows the same holiday schedule as federal offices.
In 2026, mail won't be delivered on Sundays, nor the following dates: Jan. 1, Jan. 19, Feb. 16, May 25, June 19, July 4, Sept. 7, Oct. 12, Nov. 11, Nov. 26, and Dec. 25.
Please keep in mind that occasionally, particularly near holidays, your local post office may be open, but closes earlier than usual.
