All branches of the United States Post Office will be closed Monday Feb. 17 in observance of Presidents Day, meaning mail delivery will also be halted until Tuesday, Feb. 18. Along with mail service being suspended for the federal holiday, the stock market and most banks will also be closed.

U.S. post offices will close for a day next week in recognition of a national holiday.

Presidents Day – celebrated this year on Monday, Feb. 17 – is a federal holiday, meaning all government offices are closed, including the U.S. Postal Service and all post office branches. No mail will be delivered on that day, though FedEX and UPS will be offering service on a modified schedule.
