September 30 is a weird day. Most people just see it as the end of the month—the final hurdle before spooky season officially kicks in. But if you’re looking for a September 30 holiday, you’re actually looking at one of the most culturally dense days on the calendar. It isn't just one thing. Depending on where you are standing on the planet, it’s a day of deep mourning, a celebration of global communication, or a very specific reason to eat a podcast-sized amount of cider donuts.
Honestly, the "main" event is the National Day for Truth and Reconciliation in Canada. It’s heavy. It’s important. But it’s not the only thing happening. We also have International Translation Day and some quirky food observances that keep things from getting too somber.
The National Day for Truth and Reconciliation: Why Everyone is Wearing Orange
If you are in Canada or follow international news, you’ve probably seen the sea of orange shirts on September 30. This is the big one. It’s colloquially known as Orange Shirt Day.
It started with a woman named Phyllis Webstad. Back in 1973, she was six years old and headed to a residential school. Her grandmother bought her a shiny new orange shirt. She was proud of it. But when she got to the school, the authorities stripped her, took her clothes away, and she never saw that orange shirt again. That story became a symbol for the stripping away of culture, freedom, and self-esteem experienced by Indigenous children over generations.
The Canadian government officially made September 30 a federal statutory holiday in 2021. It was a direct response to the Truth and Reconciliation Commission’s Call to Action number 80. It’s a day for reflection. You’ll see people wearing orange to honor the "Every Child Matters" movement. It’s not a "holiday" in the sense of a fun day at the beach; it’s a day to sit with some very uncomfortable history.
The Logistics of the Day
- Federal Employees: They get the day off.
- Banks and Post Offices: Generally closed across Canada.
- Private Companies: This is where it gets tricky. It varies by province. In places like British Columbia and Prince Edward Island, it's a provincial stat holiday. In Ontario? Not so much, though many businesses choose to observe it anyway.
International Translation Day: The Saint Jerome Connection
Switching gears entirely. September 30 is also International Translation Day.
Why today? Because it’s the feast day of St. Jerome. He’s the guy who translated the Bible into Latin (the Vulgate). He’s basically the patron saint of anyone who has ever struggled to explain what "déjà vu" actually feels like in another language.
The United Nations officially recognized this in 2017. It’s a nod to the fact that without translators and interpreters, global diplomacy would basically be a bunch of people shouting at each other in different rooms. In a world increasingly driven by AI—ironic, I know—human translation remains the gold standard for nuance and cultural context.
If you know someone who works in localization or spends their days deep in CAT tools, buy them a coffee today. They are the reason you can read a Murakami novel in English or watch Squid Game with subtitles that actually make sense.
Blasphemy Day: A Very Different Kind of Observance
This one is controversial. September 30 is also International Blasphemy Rights Day.

It was started in 2009 by the Center for Inquiry. The date wasn't chosen at random; it marks the anniversary of the 2005 publication of the Jyllands-Posten Muhammad cartoons in Denmark. The goal isn't necessarily to be "edgy" or mean-spirited, though it often gets interpreted that way. The core intent is to advocate for freedom of speech and the right to criticize religious beliefs without fear of legal prosecution or violence.
In some countries, blasphemy is still a capital offense. This "holiday" is a reminder of that legal reality. It’s a day for secularists and free-speech advocates to highlight the struggle for expression in places where religious law dictates public life.
The Fun Stuff: Hot Mulled Cider and Chewing Gum
Look, not every September 30 holiday needs to be about international law or historical trauma. Sometimes you just want a snack.
National Hot Mulled Cider Day
Fall is peaking. The air is crisp. It’s the perfect time for National Hot Mulled Cider Day.
Basically, you take apple cider and simmer it with cinnamon sticks, cloves, and maybe some orange peel. If you’re feeling spicy, a splash of bourbon doesn’t hurt. It’s one of those "unofficial" food holidays that actually makes sense for the weather. It marks the transition from iced lattes to warm mugs.
The Chewing Gum "Birthday"
Some people track the anniversary of chewing gum to this date. On September 30, 1848, John Curtis produced the first commercial chewing gum, called "State of Maine Pure Spruce Gum."

Before this, people were just chewing on bits of resin or wax. Curtis figured out how to boil it, skim the impurities, and roll it into sticks. It was a game-changer for people who like to fidget with their mouths.
What’s Actually Open on September 30?
This depends entirely on your coordinates.
In the United States, September 30 is a normal business day. There are no federal closures. Schools are open. Mail is delivered. It’s basically just "Tuesday" (or whatever day it falls on).
In Canada, it’s a different story. As mentioned, federal offices are shut. If you need to hit the bank or the passport office, you’re out of luck. Retail stores usually stay open, but they might have shortened hours, especially in provinces that have fully adopted the Truth and Reconciliation holiday.
In Botswana, September 30 is Botswana Day. It’s their Independence Day. It’s huge. We are talking parades, traditional dancing, and massive celebrations. They gained independence from the UK in 1966, and they take this day very seriously. If you find yourself in Gaborone today, expect a party.
Real Talk: Why This Date Matters More Than You Think
Usually, the end of a month is just a logistical deadline. But September 30 sits at a crossroads. It’s the end of the third fiscal quarter for most businesses. That means "Q3" ends today.
Business owners are scrambling. Sales teams are trying to hit their targets. It’s a high-stress day in the corporate world. Honestly, that’s why some of these smaller holidays—like the mulled cider one—actually catch on. People need a reason to breathe.
Misconceptions About the Date
- Is it a global holiday? No. There is no one-size-fits-all holiday for this date.
- Is it Always Orange Shirt Day? Yes, the date is fixed to September 30 to coincide with the time of year when children were traditionally taken from their homes to residential schools.
- Does everyone get the day off? Only if you’re in a specific jurisdiction (like Botswana or a federal worker in Canada).
How to Observe September 30 Without Being Weird
If you want to actually "celebrate" or acknowledge the day, don't try to do everything. It’s a bit of a tonal nightmare to celebrate "Blasphemy Day" and "Truth and Reconciliation Day" at the exact same time.
If you’re in Canada:
Wear orange. Read a book by an Indigenous author like Robin Wall Kimmerer or Thomas King. Acknowledge the land you’re on. It sounds small, but it’s the point of the day.
If you’re a language nerd:
Send a "thank you" note to a translator. Or, better yet, try to learn five new words in a language you’ve always been curious about.
If you’re just tired:
Make the cider. Seriously. Get the good stuff from a local orchard, throw it in a slow cooker, and let your house smell like autumn.
Actionable Steps for September 30
- Check your local calendar. If you have meetings in Canada or Botswana, double-check that your contacts aren't out of the office.
- Review your Q3 goals. Since it’s the last day of September, it’s the natural time to audit your year. What worked? What didn't?
- Support Indigenous businesses. If you're buying an orange shirt, make sure the proceeds actually go to Indigenous-led organizations or the Orange Shirt Society. Avoid the "fast fashion" knockoffs.
- Grab some mulling spices. You can buy them pre-mixed or just toss cinnamon, cloves, and allspice into a pot. It’s the easiest way to reset your mood for the evening.
- Update your translation software. If you work in business, today is a good reminder to ensure your localization tools are actually up to date before you head into the Q4 rush.
September 30 isn't just a placeholder on the way to October. It’s a day of memory and a day of communication. Whether you are reflecting on history or just trying to finish your quarterly reports, there is a lot more going on today than meets the eye.
