President's Day, known also as Washington's Birthday, is a federal holiday, meaning many government institutions will close including banks, courts and the stock markets. If you hear anyone call it "Presidents Day", you have my permission to beat them around the head with a stick.
To take the presidents quiz, click or tap and drag the portraits to put each president under the dates he was in office. Some states have Presidents' Day as a holiday; others use President's Day.
The library will be open from 10 a.m.to 5 p.m., but its research room will be closed because Monday is a federal holiday.
Washington's birthday is actually on February 22.
The weekend also marks the final chance for visitors to see the museum's painting of Washington's war tent during the Revolutionary War. (Officially, the holiday honors only the first president because it's listed as "Washington's Birthday" in federal law).
Past Presidents have often recognized the holiday with visits to Washington's tomb. Rep. William Moore McCulloch of OH argued that perhaps we wouldn't want to pay tribute to all presidents.
That schools and many businesses are taking today off can be credited to the holiday's conforming to the Uniform Monday Holiday Act, which in 1968 combined most holidays into a standard three-day package. Some lawmakers have objected to this view, arguing that grouping George Washington and Abraham Lincoln together with less successful presidents minimizes their legacies.
In its modern form, Presidents' Day is used by many patriotic and historical groups as a date for staging celebrations, reenactments and other events.
