The United States Postal Service (USPS) will not deliver mail on Presidents' Day 2018 (January 19), according to their official website. President's Day is a federal holiday, so all federal offices are closed. However, the USPS will still deliver Amazon packages on Sunday, before the holiday. All Post Offices will reopen on Tuesday, February 20, 2018.

The good news: UPS and FedEx will still deliver on Presidents' Day. This means you should still receive packages from UPS and FedEx on time. You can find the complete list of holidays for 2018 on the UPS and FedEx websites.

Here are the upcoming postal holidays, according to USPS: Memorial Day (May 28), Independence Day (July 4), Labor Day (Sept. 3), Columbus Day (Oct 3), Veterans' Day (Nov. 12), Thanksgiving Day (Nov. 22), and Christmas Day (Dec. 25).

Presidents' Day always falls on the third Monday of February each year. It marks the birthday of George Washington -- the first president of the United States -- who was born on Feb. 22, 1732. The holiday also honors Abraham Lincoln, the country's 16th president, who was born on Feb. 12, 1809. The first celebration of Presidents' Day happened in 1897 by an Act of Congress, according to history.com. President Rutherford B. Hayes signed it into law. The holiday initially only applied to the District of Columbia, but in 1885 it was expanded to the whole country.
