You’d think a month as pretty as May would be packed with days off, but honestly, there is only one big one. Just one. Federal holidays in May are actually a bit of a lonely club, consisting entirely of Memorial Day.
People get confused. They see Cinco de Mayo or Mother’s Day on the calendar and assume the post office is closing. Nope. It’s basically just the last Monday of the month that carries the heavy weight of federal law behind it.
The history of how we ended up with this specific holiday is actually kind of messy. It wasn’t always a Monday. It wasn’t even always called Memorial Day. It started as Decoration Day, a grassroots effort by grieving families to literally decorate the graves of Civil War soldiers.
The Memorial Day Shift: Why the Date Actually Matters
For a long time, the holiday was fixed on May 30. Why? Because the flowers were in bloom. It was that simple. General John A. Logan, who headed up an organization for Northern Civil War veterans, picked the date because it wasn't the anniversary of any particular battle. He wanted the day to be about the people, not the combat.
Then came the Uniform Monday Holiday Act.

This is where the federal government decided that long weekends were better for the economy than mid-week observances. In 1968, they moved Memorial Day to the last Monday in May. It took effect in 1971. Some veterans' groups, like the VFW, actually hated this. They felt that by making it a floating Monday, we were just turning a day of mourning into a car sales event and a lake trip. They weren't entirely wrong, were they?
If you look at the U.S. Code—specifically 5 U.S.C. § 6103—you'll see the official list. Memorial Day sits there alongside Christmas and Independence Day.
What Actually Closes?
When we talk about federal holidays in May, the "federal" part is the most important word. It means the federal government stops.
- The Mail: USPS is a federal entity. No mail.
- The Banks: Most follow the Federal Reserve schedule. Since the Fed is closed, your local branch is likely locked up too.
- Social Security Offices: Don't try to go. They’re dark.
- Federal Courts: Jurors get a break.
Private businesses? That’s a total toss-up. There is no law in the United States that forces a private employer to give you a paid day off for federal holidays in May or any other month. Most do it because they want to keep their employees from quitting, but it’s not a legal requirement. Retail and hospitality workers usually see these days as their busiest shifts of the year.
The Misconception of "May Holidays"
We have a habit of inflating May.
Take Mother’s Day. It feels like a national holiday. It’s massive. But it’s a "designated" observance, not a federal holiday. Same goes for Peace Officers Memorial Day (May 15) or National Maritime Day (May 22). These are created by Presidential proclamation, but they don't give you a day off. You still have to go to work. Your boss still expects those emails.
Then there’s Cinco de Mayo. People love it. It’s a huge cultural moment, especially in the Southwest. But it’s not a federal holiday in the U.S., and ironically, it’s not even a major national holiday in most of Mexico—it’s primarily celebrated in the state of Puebla.
Why Memorial Day is Often Confused with Veterans Day
This is the big one. The one that gets people into trouble on social media.

Memorial Day is for those who died while serving. It’s somber. It’s heavy.
Veterans Day (in November) is for everyone who served.
When you say "Happy Memorial Day" to a veteran who is standing right in front of you, it can feel a bit awkward. For them, the day is about the friends who didn't come home. It’s why you’ll see some people get prickly about the "Happy" part of the greeting. It’s a day of remembrance, not just a day for a barbecue.
The Economic Engine of the Last Monday in May
While the federal government sees a day of rest, the business world sees a gold mine. Memorial Day is widely considered the "unofficial start of summer."
Travel spikes. AAA usually reports that tens of millions of people hit the road. This creates a weird paradox where a holiday meant for reflection becomes one of the most stressful travel windows of the year. Gasoline prices usually tick up. Hotels in coastal towns reach peak capacity.
If you are looking at federal holidays in May through the lens of a "lifestyle" choice, you’re basically choosing between two paths:
- The quiet route: Visiting a national cemetery or a local monument.
- The loud route: Fighting traffic to get to a beach.
Logistics and Planning for the May Federal Holiday
If you’re planning a move or need to handle government paperwork, May is a tricky month. Since Memorial Day falls at the very end of the month, the "Tuesday after" is often one of the busiest days of the year for local DMVs and government offices. Everybody waits until the holiday is over to handle their business, creating a massive backlog.
If you have a passport that needs renewing or a permit that’s expiring, do it in the first two weeks of May. Don't wait for that final week. The system grinds to a halt.

Actionable Insights for Navigating May
To handle the month effectively, you should separate the "calendar events" from the "legal holidays."
Check your local school district. Just because the federal government is closed doesn't mean your kid's school is—though most do align with the federal schedule. Some districts use Memorial Day as a "makeup day" if they had too many snow days in the winter.
Watch the "Friday Before." For many federal employees, the Friday before Memorial Day is a "liberal leave" day. This means offices might be technically open, but they are running on a skeleton crew. If you need to reach a specific person at a federal agency, call them by the Thursday of that week.
Understand the Flag Code. If you’re flying a flag for the federal holiday, the tradition is to fly it at half-staff until noon, then raise it to full-staff until sunset. This symbolizes honoring the dead in the morning and the living veterans' resolve in the afternoon.
Manage Your Banking. Digital transfers (ACH) don't move on federal holidays. If you have a bill due on that last Monday in May, the payment likely won't process until Tuesday. Schedule your online payments to go out by the preceding Friday to avoid any late fees.
The reality of federal holidays in May is that they are rare but significant. We get one chance to pause, and it happens right as the weather turns warm. Understanding the distinction between a "day people celebrate" and a "day the government closes" is the key to not getting caught with an empty mailbox and a closed bank branch. Use the middle of the month to get your chores done so you can actually enjoy the one day off the feds give you.
