National Mathematics Day – go to Bedtime Math!
Dongzhi Festival: the days are getting longer from this day and so more positive yang energy will come in. People eat tangyuan.
Ziemassvētki (ancient Latvia): Candles are lit for spirits and a fire is kept burning until the end, when its extinguishing ends the year’s unhappiness. A feast is served with bread, beans, peas, pork, and pig snout and feet, with a space at the table is reserved for ghosts, who arrive on a sleigh.
