This very simple idea - a candle with the numbers 1 through 24 along the length - is probably one of the most incorporated Danish traditions. Every family and almost every classroom has their own countdown candle, usually decorated with pine, bows or moss in a christmas decoration. The idea is that you burn what accounts to one number (one date) every day.

The thickness of the candle seems to be proportional to how busy each family is - a thin one can burn from one date to the next in 20 minutes. My family is a giant hygge-bomb so of course we always get the thickest candle my mom can get her hands on. It takes forever to burn. It needs to be lit at least 3 hours pr day if you want to keep up with the dates.
