    Winter Solstice – Tuesday, December 21, 2021

    The winter solstice, also called the hiemal solstice, hibernal solstice, and brumal solstice, occurs when either of Earth’s poles reaches its maximum tilt away from the Sun. This happens twice yearly, once in each hemisphere. For that hemisphere, the winter solstice is the day with the shortest period of daylight and longest night of the year, when the Sun is at its lowest daily maximum elevation in the sky. Either pole experiences continuous darkness or twilight around its winter solstice. The opposite event is the summer solstice. Depending on the hemisphere’s winter solstice, at the Tropic of Cancer or Capricorn, the Sun reaches 90° below the observer’s horizon at solar midnight, to the nadir.
