Winter Solstice
The point in the Earth's orbit where one of its poles is pointing directly away from the Sun, at an angle of more than 23°. This effect results in the shortest day of the year in the hemisphere of the pole in question. The Winter Solstice occurs on or about 21 December in the northern hemisphere, and on or about 21 June in the southern hemisphere.
