More evident from high latitudes, a hemisphere's winter solstice occurs on the day with the shortest period of daylight and longest night of the year, when the sun's daily maximum elevation in the sky is at its lowest. Although the winter solstice itself lasts only a moment in time, the term sometimes refers to the day on which it occurs.
The declination of the Sun on the (northern) winter solstice is known as the tropic of capricorn (-23Â° 27'). The winter solstice is the shortest day of the year, respectively, in the sense that the length of time elapsed between sunrise and sunset on this day is a minimum for the year.
