How many weeks until Twelfth Night - SE?

In many countries, Twelfth Night leading into Epiphany marks the absolute end of Christmas celebrations. But the Swedes and Finns, and some parts of Norway, feel it's a pity to finish that early, and stretch Christmas another week. That gives the final date of January 13th, which in Sweden is the name day of Knut, hence the expression tjugondedag Knut ("twentieth day Knut").See nordstjernan for more details.
