2024 US Holiday Calendar: What Actually Matters
Most people just need a straightforward list of dates. The federal holidays are easy enough, but the real problem starts when you try to coordinate around everything else. I spent three years managing scheduling for a team spread across multiple states, and let me tell you, the standard "holiday calendar" people hand out is basically useless once you add in religious observances, state-specific days, and the stuff that actually disrupts business. Here's what actually matters for 2024, stripped of the marketing language. Federal Holidays:
New Year's Day — January 1. Presidents' Day — third Monday in February (February 19). Memorial Day — last Monday in May (May 27). Independence Day — July 4. Labor Day — first Monday in September (September 2). Columbus Day / Indigenous Peoples' Day — second Monday in October (October 14). Veterans Day — November 11. Thanksgiving — fourth Thursday in November (November 28). Christmas — December 25. Those are the ones that close government offices and most banks. But if you're planning anything beyond a basic schedule, that's only the beginning. Religious and Cultural Observances That Actually Affect Business:
Passover — April 22 through April 30. Eid al-Fitr (end of Ramadan) — approximately March 10-11. Good Friday — March 29. Easter Sunday — March 31. Diwali — November 1. Hanukkah — December 25 through January 2, 2025. Lunar New Year — February 10. Tisha B'Av begins at sunset July 13. The tricky part here isn't the dates themselves. It's that some of these shift every year because they follow lunar or lunisolar calendars. If you're setting up reminders or automated systems, you can't just hardcode these. You need a rolling calendar source.

What Most People Miss When Building Their Calendar
I learned this the hard way in 2022 when we scheduled a company-wide offsite for a date that fell during Passover. Half our team couldn't attend because they were observing the holiday, and we'd completely missed it on our master calendar. The problem was that we were relying on a single source — a generic PDF — that only listed federal holidays and maybe two or three religious observances. It wasn't comprehensive by any standard. The workaround I ended up using was combining multiple sources. I pulled federal dates from USA.gov, cross-referenced religious dates from religiouscalendar.org and the ADL's interfaith calendar, and then added state-specific observances manually based on where our team members lived. For example, Texas observes Confederate Memorial Day on January 19. California celebrates Cesar Chavez Day on March 31. Massachusetts and Maine observe Patriots' Day on the third Monday in April. If you have a distributed team, these state holidays matter more than you'd think. One thing nobody tells you: many religious holidays also have practical scheduling implications beyond the day itself. Yom Kippur is a full 25-hour fast from sunset to nightfall the following day. If someone requests that day off, they might also need flexibility the afternoon before or the morning after. Same thing with Eid — the celebration often spills into the following day. Building tolerance into your schedule for these edge cases saves you from last-minute scrambling.
State-Specific Holidays You Shouldn't Ignore
Beyond the federal list, individual states observe holidays that can affect your operations if you have employees or clients there. Here are the notable ones for 2024: Alabama and Tennessee: Confederate Memorial Day, April 26. Arkansas: Jefferson Davis Birthday, third Monday in January (January 15). Florida: Martin Luther King Jr. Day is observed, but they also recognize Confederate Memorial Day. Georgia: Martin Luther King Jr. Day is combined with Confederate Memorial Day on the third Monday in January. Idaho: Martin Luther King Jr. Day is observed as "Idaho Human Rights Day." Illinois: César Chávez Day, March 31. Kentucky: Martin Luther King Jr. Day / Robert E. Lee Birthday, third Monday in January. Mississippi: Martin Luther King Jr. Day / Robert E. Lee Birthday, third Monday in January. Missouri: Martin Luther King Jr. Day / Robert E. Lee Birthday, third Monday in January. Nevada: Martin Luther King Jr. Day / Robert E. Lee Birthday, third Monday in January. North Carolina: Confederate Heroes Day, January 19. Oklahoma: Native American Holiday, first Friday after Columbus Day (October 18). South Carolina: Robert E. Lee Birthday, third Monday in January. Tennessee: Lee-Jackson Day, day before Martin Luther King Jr. Day (January 15). Texas: Confederate Memorial Day, January 19. Virginia: Martin Luther King Jr. Day / Robert E. Lee Birthday, third Monday in January. That's a lot of variation. If you're managing a national team, you can't reasonably keep track of all of this manually. I recommend using a service like Timeanddate.com or loading a subscribed calendar from your government's official calendar page. The US government publishes an .ics file you can import directly into Google Calendar or Outlook.
How to Actually Make This Work in Practice
Here's what I do now when I need a working calendar for planning purposes: First, I start with the federal holidays. Those never change dates in the same way — they're all "third Monday in February" or "last Monday in May" type rules, which most calendar apps handle automatically. Second, I layer in the major religious observances that affect my team. I don't try to track every single one. I focus on the ones where people actually take time off — Passover, Rosh Hashanah, Yom Kippur, Eid, Diwali, Hanukkah, Chinese New Year. For the shifting dates, I set calendar reminders three months before each year's dates are announced so I can update my plans.
Third, I add state holidays that are relevant to where my people live. This usually means checking against a state-by-state reference. The National Conference of State Legislatures maintains good information on this. The whole process takes me about 45 minutes the first time I set it up for the year, and maybe 10 minutes each year after that to update the shifting dates. Not bad for something that would otherwise cause constant friction.
The Real Limitation Nobody Talks About
Even with all of this, a static calendar will always fall short. The problem is that observance is personal. Two people from the same religion might observe the same holiday completely differently. Someone who identifies as culturally Jewish might not observe Passover at all, while someone else in their family might fast for the entire day. A calendar can't capture that nuance. My advice: treat any published calendar as a starting point, not a source of truth. The only way to know for certain whether someone is observing something is to ask them. I make it a habit to send out a brief check-in to my team each quarter asking if anyone has personal or religious observances coming up that we should plan around. It takes about five minutes and prevents a lot of awkward situations. Also worth noting: corporate calendars tend to underrepresent non-Christian holidays. If you're building a calendar for a diverse organization, you're probably missing half the observances that actually matter to your people. I've seen this repeatedly. The "inclusive" holiday calendars I've encountered usually include Christmas, Easter, Thanksgiving, and maybe Hanukkah. That's it. Everything else — Ramadan, Diwali, Lunar New Year, Eid al-Adha, Rosh Hashanah — gets left out or pushed to a footnote. It's a real problem and it's still common enough that I feel obligated to mention it.
If you want actual downloadable resources, the Office of Personnel Management at opm.gov publishes the official federal holiday calendar each year. For religious observances, the Interfaith Calendar at interfaithcalendar.org is one of the more reliable free sources I've found. It's not perfect but it's better than what most people use.
