You’re staring at your calendar, trying to figure out if you actually have to log in tomorrow or if the bank is going to be closed when you try to deposit that check. It’s a classic Tuesday-brain problem on a Sunday night. Honestly, the answer to "is Monday a legal holiday" isn’t as straightforward as a simple yes or no because it depends entirely on which Monday we're talking about and who you work for.
Basically, the United States doesn't have "national" holidays in the way other countries do. There is no law that forces a private business in Des Moines or a coffee shop in Seattle to close just because it's a federal holiday.

The Monday Holiday Rule
Back in 1968, Congress did something kind of rare: they actually made life a little easier for the average person. They passed the Uniform Monday Holiday Act. Before this, holidays like Washington’s Birthday were celebrated on their actual birth dates, which meant they often landed on awkward Tuesdays or Thursdays.
The government realized people wanted three-day weekends. So, they moved several major holidays to specific Mondays. This is why you’ll notice a pattern. Martin Luther King Jr. Day is always the third Monday in January. Presidents' Day (officially Washington's Birthday) is the third Monday in February. Memorial Day? Last Monday in May. Labor Day? First Monday in September. Columbus Day/Indigenous Peoples' Day? Second Monday in October.
If today is one of those specific Mondays, then yes, it is a legal holiday for federal employees.
What happens when a holiday falls on a Sunday?
This is where people get tripped up. If a fixed-date holiday—like Independence Day or Christmas—lands on a Sunday, the legal "observation" usually moves to the following Monday.
In 2026, for example, July 4th falls on a Saturday. In that case, the "legal holiday" for most federal workers is actually the Friday before. But if Christmas were on a Sunday, that Monday would become the legal holiday. It’s a bit of a shell game played by the Office of Personnel Management (OPM) to make sure government workers don't lose their paid day off just because the calendar was being difficult.
Who actually gets the day off?
If you work for the post office, a federal court, or a government agency, you're likely staying in bed. Banks usually follow the Federal Reserve schedule, so they’re typically closed on these Mondays too.
Private companies? That’s a total toss-up.
- Tech and Corporate: Most big white-collar firms mirror the federal schedule for the "big" ones like Labor Day and Memorial Day.
- Retail and Service: Forget about it. For retail, a Monday holiday is just "Sale Day."
- Small Businesses: These are the wild cards. A local mom-and-pop shop might close for Memorial Day but stay open for Columbus Day.
There is no federal law—none at all—that requires private employers to pay you for not working on a legal holiday. It’s strictly a matter of your employment contract or company handbook.
State vs. Federal: The 2026 Landscape
Sometimes a Monday is a legal holiday in one state but perfectly normal in the next one over. Take Good Friday, for instance. It's not a federal holiday, but in states like Connecticut, Delaware, and Louisiana, it’s a state-level legal holiday.
In 2026, we're seeing some interesting shifts. On January 12, 2026, reports surfaced about changes to how certain holidays are administered at the federal level. While the holidays themselves stay on the calendar, the "perks"—like fee-free days at National Parks—are being tweaked by the current administration.
Is Monday a legal holiday for the stock market?
The New York Stock Exchange (NYSE) and Nasdaq generally follow the federal Monday holiday schedule, but they aren't perfectly in sync. They close for the "major" Mondays (MLK, Presidents' Day, Memorial Day, Labor Day) but they stay open on Veterans Day and Columbus Day/Indigenous Peoples' Day, even though those are federal holidays.
If you’re looking to trade stocks on a Monday, you’ve got to check the specific exchange holiday list, not just the bank calendar.
Real-world impact on deadlines
If you have a legal deadline—like filing your taxes or responding to a court summons—and that Monday is a legal holiday, the law usually gives you a "grace" day. Under Rule 6 of the Federal Rules of Civil Procedure, if a deadline falls on a legal holiday, the period continues to run until the end of the next day that isn't a Saturday, Sunday, or legal holiday.

Actionable Steps for Your Monday
- Check the Federal Reserve Schedule: If you need to do "in-person" banking, visit the Federal Reserve’s official site. If they’re closed, your local branch is almost certainly closed.
- Review Your Employee Handbook: Don't assume. Some companies trade "lesser" holidays like Columbus Day for a longer break at Thanksgiving.
- Confirm Mail Delivery: The USPS doesn't deliver regular mail on federal Monday holidays. However, UPS and FedEx often do operate, though sometimes with modified service.
- Check Local Parking Rules: This is a sneaky one. Many cities don't enforce parking meters on "legal holidays." You could save twenty bucks just by knowing it’s a holiday Monday, even if you still have to go to work.
If you are trying to figure out if tomorrow specifically is a holiday, look for the big five: MLK Day (Jan), Presidents' Day (Feb), Memorial Day (May), Labor Day (Sept), or Columbus Day (Oct). If it’s one of those, the "legal" status is a yes.
Next Steps:
To be 100% certain for your specific situation, verify your state's official "Green Book" or state government website, as state-level legal holidays can vary significantly from the federal calendar. If you're dealing with a legal filing, always confirm with the specific clerk of court, as local rules can occasionally differ regarding "observed" dates.
