When does the traditional Polish festival of "Wigilia" take place?

Traditionally, the celebration of Christmas in Poland begins on the evening of December 24th. This day is called Wigilia. Wigilia is the traditional Christmas Eve vigil supper in Poland. People are convinced in the fact that in the way they spend Christmas Eve the whole year will pass. Therefore, they try to make this day really fabulous and warm.

The word Wigilia derives from the Latin vigil. The associated feasting follows a day of abstinence and traditionally begins once the First Star has been sighted.[1] Christmas is also sometimes called "Gwiazdka", "little star".
