21 or 22 December:  *Winter solstice :  The winter solstice occurs exactly when the axial tilt of a planet is farthest away from its star, depending on the polar hemisphere of reference. Earth’s maximum axial tilt to our Sun during a solstice is 23° 26′. More evidently from high latitudes, a hemisphere’s winter solstice occurs on the shortest day and longest night of the year, when the sun’s daily maximum position in the sky is the lowest.[2] Since the winter solstice lasts only a moment in time, other terms are often used for the day on which it occurs, such asmidwinterthe longest night or the first day of winter.
