Monday is a holiday so often because Congress designed it that way. The Uniform Monday Holiday Act, signed in 1968 and effective January 1, 1971, moved several federal holidays off their fixed calendar dates and pinned them to designated Mondays, guaranteeing three-day weekends and ending the midweek shutdowns that had frustrated employers, schools, and the government itself.1U.S. Government Publishing Office. Public Law 90-363 – Uniform Monday Holiday Act Five federal holidays now always land on a Monday, and a few others get observed on Mondays when their fixed dates happen to fall on a Sunday.
What the 1968 Law Changed
Before 1971, holidays like Memorial Day and Washington’s Birthday sat on fixed calendar dates. A holiday could land on any weekday, and a Wednesday holiday split the workweek in half. Public Law 90-363, passed on June 28, 1968, addressed that by shifting four holidays to Monday slots: Washington’s Birthday, Memorial Day, Veterans Day, and Columbus Day.1U.S. Government Publishing Office. Public Law 90-363 – Uniform Monday Holiday Act
President Lyndon Johnson framed the reasoning in economic terms when he signed the bill, saying Monday holidays would “stimulate greater industrial and commercial production, sparing business and labor the penalty of midweek shutdowns.”2The American Presidency Project. Statement by the President Upon Signing the Uniform Holiday Bill Longer weekends also meant more travel and tourism spending, and fewer interruptions to federal operations. The premise was simple. If the country is going to take a day off, that day should connect to the weekend.
The Five Holidays That Always Fall on a Monday
Five federal holidays are permanently anchored to a specific Monday under 5 U.S.C. § 6103(a), the statute listing every legal public holiday:3Office of the Law Revision Counsel. 5 USC 6103 – Holidays
- Martin Luther King Jr. Day, the third Monday in January
- Washington’s Birthday, the third Monday in February (widely called Presidents’ Day, though the federal statute uses only “Washington’s Birthday”)
- Memorial Day, the last Monday in May
- Labor Day, the first Monday in September
- Columbus Day, the second Monday in October (increasingly recognized as Indigenous Peoples’ Day by states and localities)
Three of these came from the 1968 Act itself. Labor Day was already a Monday holiday before the law passed. Martin Luther King Jr. Day was added later: President Reagan signed Public Law 98-144 in 1983, and the holiday was first observed on the third Monday in January 1986.4Congress.gov.

The Holiday That Went Back to Its Original Date
Veterans Day is the one holiday where the Monday experiment failed. The 1968 Act moved it to the fourth Monday in October, and the first observance under the new schedule in 1971 met immediate resistance. Veterans’ organizations objected that November 11 carried specific historical meaning as the date World War I ended, and moving it to a generic Monday diluted that.5U.S. Department of Veterans Affairs. History of Veterans Day
States started ignoring the federal date almost immediately. By 1975, 46 of the 50 states had either switched back to November 11 or refused to change in the first place. Congress responded with Public Law 94-97, which President Ford signed on September 20, 1975, returning Veterans Day to November 11 beginning in 1978.5U.S. Department of Veterans Affairs. History of Veterans Day So Veterans Day now falls on whatever weekday November 11 happens to be.
Why Other Holidays Still End Up on Mondays
Even holidays that aren’t part of the Monday framework sometimes get observed on a Monday. Six federal holidays sit on fixed calendar dates: New Year’s Day, Juneteenth, Independence Day, Veterans Day, Thanksgiving (always a Thursday), and Christmas. When one of the fixed-date holidays falls on a Sunday, federal employees get the following Monday off under Executive Order 11582, which directs that employees “shall be excused from work on the next workday” whenever a holiday falls on Sunday.6National Archives. Executive Order 11582
When a fixed-date holiday falls on a Saturday, the preceding Friday becomes the observed day for employees on a standard Monday-through-Friday schedule.3Office of the Law Revision Counsel. 5 USC 6103 – Holidays Between the five Monday-anchored holidays and the Sunday-shift rule for the fixed-date ones, Mondays end up hosting more federal holidays than any other day of the week.
What a Monday Holiday Actually Changes
Federal Monday holidays close government offices, but the effects reach further than that. Legal filing deadlines shift: under the Federal Rules of Civil Procedure, when the last day of a filing period falls on a Saturday, Sunday, or legal holiday, the deadline rolls to the next business day.7Legal Information Institute. Rule 6 – Computing and Extending Time Tax deadlines work the same way under 26 U.S.C. § 7503.8Office of the Law Revision Counsel. 26 USC 7503 – Time for Performance of Acts Where Last Day Falls on Saturday, Sunday, or Legal Holiday A brief or return due on a Monday holiday isn’t late if filed Tuesday.
The Federal Reserve closes on every federal holiday, so no interbank transfers or check clearing happens on those days.9Federal Reserve Board. Holidays Observed – K.8 If you’re wiring money or waiting on a payment to settle around a Monday holiday, add a day to the timeline.
One boundary worth naming: the federal holiday schedule doesn’t require your private employer to give you the day off or pay you extra for working it. Section 6103 applies to federal government employees and the District of Columbia.3Office of the Law Revision Counsel. 5 USC 6103 – Holidays The Department of Labor states that the Fair Labor Standards Act “does not require payment for time not worked, such as vacations or holidays (federal or otherwise). These benefits are generally a matter of agreement between an employer and an employee.”10U.S. Department of Labor. Holiday Pay Most private employers follow the federal calendar anyway because it aligns with banking closures, school schedules, and customer expectations, but Monday off is a matter of employer policy, not federal mandate.
