In Finland you wont see anyone on the streets celebrating loudly (Unless you go to the cemeteries where some people might take a walk and lay candles to the graves). Finns respect holiday this important by silence and peace. It would be rude to carouse on the streets.
Traditionally people mostly spend Independence Day at home with family. They eat something, probably sauteed reindeer with mashed potatoes or Karelian stew. Then, of course, there’s blue and white colored candles lighten up in front of the windows.
"The Unknown Soldier" movie from 1955 is traditionally shown in TV in the afternoon. The movie is about the Continuation War and it’s based on a book with the same name, written by Väinö Linna.
But the Main Event of Finnish independence day, the TV broadcast of President’s party, the “Castle’s Party” begins at 18:00. Traditionally we watch TV for three hours and watch as famous people and people on high position shake hands with the President Sauli Niinistö and his wife. And of course you judge all female dresses and condemn etiquette blunders.
Happy Independence Day! Hyvää itsenäisyyspäivää!
