Here's the translation in English:

In Finland, every year on July 27, 'Unikeonpäivä' or 'National Sleepyhead Day' is celebrated 😄. On this day, the person who sleeps the latest in the house is called the 'Sleepyhead' and is awakened by being thrown into water 🛀. This tradition dates back to the Middle Ages, when sleeping late was considered a sign of laziness, but now it's done for fun 🎉. In cities like Naantali, even celebrities are thrown into water 😂.

Would you like to celebrate such a national day in your country?
