Epiphany

Today is one of the traditional days to finish the Christmas celebrations and tidy up all Christmas decorations. Thank you and good bye Christmas. See you again in 300 + days...

Regarding the old law the Christmas peace was on place for 20 days and finished on 13.1. I have not found any other countries with that same tradition.

Wikipedia also tells about this "Nuutinpäivä" day only in Finnish: " 'Hyvä Tuomas joulun tuopi, paha Nuutti pois sen viepi.' Vanhojen lakien mukaan joulurauha kesti 20 päivää[2] ja päättyi siten 13. tammikuuta"
