Presidents’ Day, also known as Washington's Birthday, is observed on the third Monday in February (it falls on February 21 in 2022). Founded in honor of the first president of the United States, George Washington, the holiday later started honoring the 16th president, Abraham Lincoln (born February 12). In 1971, a bill was passed that opted to include all U.S. presidents that served in office. A federal holiday and one of the biggest shopping days of the year, many retailers (including Casper) offer promotional sales over the holiday weekend.
