October usually hits people like a ton of bricks. One minute you're sweating through the end of August, and the next, there's a crisp bite in the air and everyone is obsessed with decorative gourds. But if you actually sit down to look at what holidays are in october, it's way more than just a countdown to Halloween. It’s a messy, crowded, fascinating month for the calendar.
Honestly, it’s the transition that makes it weird. You’ve got these massive federal observations in the US, like Indigenous Peoples' Day, bumping up against global religious festivals like Diwali, which occasionally slides into the October slot depending on the lunar cycle.
It's a lot to keep track of.
Most people just think of candy and costumes. That’s fair. Halloween is a behemoth. But if you're trying to plan a work schedule or just figure out why the bank is closed on a random Monday, you need the full picture.
The Big Hitters: Federal and Major Observances
Let's talk about the second Monday of the month. This is where things get a bit complicated in the United States. Traditionally, this was Columbus Day, established as a federal holiday in 1937. However, the vibe has shifted significantly over the last decade. Now, many states and cities officially recognize it as Indigenous Peoples' Day.
It’s a federal holiday regardless of what your local municipality calls it. This means the post office is locked up tight, and the bond markets take a breather. If you’re a government employee, you’re likely off. If you work in tech or retail? Probably not. It's one of those "check your handbook" kind of days.
Then there’s the big one. Halloween.
October 31st isn't a federal holiday, which always felt like a personal insult when I was a kid. But it's arguably the most culturally significant day of the month. It’s grown into a multi-billion dollar industry. According to the National Retail Federation, Americans consistently spend over $10 billion annually on everything from giant 12-foot skeletons to those tiny fun-sized Snickers that somehow taste better than the full-sized ones.
Why the Date Matters for Halloween
Halloween’s roots are in the ancient Celtic festival of Samhain. People believed that on this night, the boundary between the living and the dead got thin. Real thin. They wore costumes to scare off ghosts. Fast forward a few thousand years, and now we just dress up like memes or superheroes and ask neighbors for Twizzlers. It’s a strange evolution, but it works.

Beyond the Pumpkin Spice: Religious and Cultural Days
When you're looking at what holidays are in october, you have to look globally. The month is heavy with religious significance for millions of people.
Yom Kippur, the holiest day in Judaism, often falls in early October (though it can hit late September). It’s a day of fasting and reflection. If you have colleagues or friends observing, it’s good to know that this isn't a "celebration" in the party sense—it’s a somber, deeply spiritual period of atonement.
Then there’s Diwali.
The Festival of Lights is massive. While it often lands in November, it frequently graces late October. It marks the victory of light over darkness. If you’ve ever seen a neighborhood lit up with diyas (small oil lamps) and smelled the incredible spread of sweets, you know why it's a highlight of the year. It's vibrant. It's loud. It’s arguably one of the most beautiful sights you’ll see all autumn.
Navaratri and Dussehra
These Hindu festivals are also key players in the October lineup. Navaratri spans nine nights of dance and worship, leading into Dussehra, which celebrates the victory of Lord Rama over the demon king Ravana. In places like West Bengal, Durga Puja transforms entire cities into open-air art galleries. The sheer scale of these events makes a typical American neighborhood "haunt" look like a backyard BBQ.
The "National Day" Rabbit Hole
We need to address the elephant in the room: those "National Days" that seem to pop up every five minutes on Instagram.
You know the ones.
National Taco Day (October 4th). National Coffee Day (usually late September, but the caffeine high carries over). National Pierogi Day (October 8th).

Are these real holidays? No. Not in the sense that you get a day off work. But for brands and social media managers, they are the bread and butter of October. October is also Breast Cancer Awareness Month, a vital period for fundraising and education that has been recognized since 1985. You’ll see the pink ribbons everywhere—from NFL cleats to yogurt lids.
There's also World Mental Health Day on October 10th. This one has gained a lot of traction recently, and for good reason. Companies are increasingly using this day to encourage "wellness days" or mental health breaks, acknowledging that the grind of the final quarter of the year can be brutal.
International Flavor: Canada and Germany
If you’re in Canada, October means Thanksgiving.
While Americans are waiting until late November to argue with their relatives over turkey, Canadians get it over with on the second Monday of October. Why so early? Harvest happens sooner up north. It makes sense. It’s a different vibe—less about "Black Friday" madness and more about actually being thankful for the crops before the ground freezes solid for six months.
And we can't ignore Oktoberfest.
Despite the name, most of Oktoberfest actually happens in September, but it traditionally ends on the first Sunday of October. If you’re in Munich—or a very enthusiastic German beer hall in Cincinnati—the first few days of October are the peak of the festivities. It’s all about the Märzen beer and lederhosen.
The Weird and the Niche
Sometimes the answer to what holidays are in october depends on how much of a nerd you are.
Take Ada Lovelace Day (the second Tuesday of October). It celebrates women in STEM. Lovelace is credited with being the first computer programmer, and this day is a cool, grassroots way of highlighting the contributions of women in tech.

Or Sweetest Day (the third Saturday in October).
If you live in the Midwest or parts of the Northeast, you probably know this one. If you live anywhere else, you’re probably confused. It’s basically "Valentine’s Day 2.0," originally started by candy companies in Cleveland in the early 1900s. It hasn’t quite conquered the world, but in places like Michigan or Ohio, it’s a legit reason to buy your partner a box of chocolates.
How to Actually Navigate October
So, what do you do with all this?
First, check your local school or office calendar for that second Monday. If you're planning a trip or a big meeting, that’s your biggest hurdle.
Second, don't sleep on the cultural festivals. If you have a local Hindu temple or a Jewish community center, see if they have public events for Diwali or Sukkot. October is one of the richest months for experiencing cultures outside your own bubble.
Third, prepare for the Halloween madness early.
Every year, people wait until October 25th to buy a costume and end up going as "person who bought a leftover onesie at Target." If you want to actually enjoy the holiday, start the DIY process or the shopping by the 10th. The "holiday" of Halloween is really a month-long season, not just a single night.
Actionable Checklist for October
- Audit your subscriptions: October 1st is a great "reset" day for monthly bills.
- Check for Bank Holidays: Remember the 2nd Monday. Your direct deposit might be delayed by 24 hours if it hits on that day.
- Flu and Booster Shots: Health experts usually recommend getting these in October to ensure peak immunity before the winter holidays.
- Garden Prep: Most "harvest" holidays remind us that it's time to put the garden to bed. Get those bulbs planted before the first frost.
October is a bridge. It’s the gap between the freedom of summer and the structured chaos of the winter holidays. Whether you're celebrating the harvest, honoring ancestors, or just eating too many Reese's pumpkins, there's a lot more going on than just a change in leaf color. Keep your calendar updated, keep an eye on the moon phases for those shifting religious dates, and maybe buy some extra candy just in case. You're gonna need it.
