We use the ISO-8601 date and time format, mostly. We separate the portions by points, not dashes, though. So a typical date looks like this: 2023.12.22.
If we shorten it without the year, it's 12.22., or 5.12.
We say it with just the numbers, without the points, and shorten "hónap" (month) to "hó". So its "5. hó 12", basically "5th mo' 12".
For time we use the 24H format, regularly even in everyday speech. If it's very clear that you are in the late afternoon or evening, you just say "6 o'clock 24" or "13 o'clock 46".
So always from bigger to smaller "powers". It's auto-sorted on most filesystems, table of contents etc. and very clear in everyday use. It's nice.
We take folk dancing very seriously. There are A LOT of folk dance ensembles and they vary from random hobbyist groups to company-sponsored groups of 80+ dancers. There are lots of competitions, drama and every 5 years - a huge concert where most ensembles participate and perform in a stadium. One dance can contain up to 1000 dancers at the same time.
During this year's final dance the spectators mentioned that they could feel the ground shaking.
The night before December 6th, children leaves their shoes on front of the chimney, along with a glass of milk and a carrot for Saint-Nicholas and his donkey (other countries say it's a horse, but it's a donkey for us).
Saint-Nicholas leaves a bunch (like, a lot) of candy and toys during the night for children to find when they wake up.
Traditional treats include speculoos, chocolate coins, nuts, clementines and "guimauve" (like marshmallows but a little less soft, in the shape of clogs or religious figures, sometimes chocolate-covered).
Also, on Easter, children will find eggs in their backyard. They are dropped by "the bells". The story is that the bells of Rome fly across Europe and drop eggs along the way (see this postcard). So when the children are done finding all the eggs, they shout "THANK YOU BELLS".
In Finland, during winter, we enjoy making wide openings into an icy lake near the shore, and go swimming in it. Best translation I can find is ice swimming. This is usually paired with a piping hot sauna, and you alternate between the 80-100 celcius hot room and taking dips in the ice water.
If no lake/similar body of water is available, rolling around naked in snow is also a valid option.
There are broadly 150 indigenous language groups but only about 14 are still in common use.
If you've worked for a single company/system for 7 years you get a bonus 6 weeks 'long-service' leave.
We have a native cherry that grows inside out called a cherry ballart.
Our cuisine is really varied depending on your geography with a lot of soth East Asian influences. Most people will make stir-fry reasonably often and we have our own variations of sushi and dim sum which would offend most Japanese or Chinese people.
Most slavic languages probably don't have spelling contests - what you say has mostly exact textual representation, except some letters that can sound alike when spoken.
This website has maps of how french words are pronounced differently depending on where people live, sometimes the words aren't even the same but still refer to the same thing!
We eat raw olive oil with bread for breakfast. Trust me, it's actually more disgusting than everyone thinks.
Imagine a country physically located in Africa that has more influence from the Arab world and the European [sub]continent than local influence. Your average citizen can speak like, 3 languages, and there's certainly some that can speak more than that. We even participated in the Eurovision Song Contest at one point (biggest regret imo).
Have you ever heard of Pokimane? What about Loreen? Chances are they have ethnic roots from this country. Oh, and Faouzia too.
There's so many mosques here. I'm not against practicing religion, but I have to say that there's probably too many mosques, when a couple hundred is more than enough for everyone. Try appropriately 40 thousand. And the state actually wants to build more.
Some Israeli company uses our argan oil for their skincare products. To this day, this remains my worst nightmare.
Hospitality.
You guys really need to try our couscous. It's delicious.
Hey, I see you mentioned the USA in your post. Well guess what. It's not France that first recognized them, it's us.
It's probably reasonably well-known, but nearly (or around) 90% of Aussies live within 50km of the coast, despite us having a landmass similar in size to the USA.
