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 2016, mail won't be delivered on Sundays, nor the following dates: Jan. 1, Jan. 18, Feb. 15, May 30, July 4, Sept. 5, Oct. 10, Nov. 11, Nov. 24, Dec. 26.
Please keep in mind that occasionally, particularly near holidays, your local post office may be open, but closes earlier in the day than usual. As Christmas falls on a Sunday in 2016, postal workers will not be working on Monday the 26th.
Here's a complete list of federal holidays and the corresponding dates in 2016 when post offices will be closed:
