During the Advent festival in Sweden, people traditionally light candles to commemorate the four Sundays leading up to Christmas. This custom signifies the anticipation of the holiday season and the light that it brings amid the winter darkness. Families often gather to light the candles, sing carols, and reflect on the festive spirit. The use of lights is an integral part of Swedish culture, not only symbolizing hope and warmth but also strengthening family bonds during this time of togetherness and celebration.
