What is does the word solstict mean?

Answer 1

Do you really mean solstice?

If so, then 'solstice' refers to the summer/winter equinox that occurs twice each year when the sun is at it's greatest distance from the celestial equator.

n.

1. Either of two times of the year when the sun is at its greatest distance from the celestial equator. The summer solstice in the Northern Hemisphere occurs about June 21, when the sun is in the zenith at the tropic of Cancer; the winter solstice occurs about December 21, when the sun is over the tropic of Capricorn. The summer solstice is the longest day of the year and the winter solstice is the shortest.
2. A highest point or culmination.

Answer 2

The term "solstict" appears to be a typographical error or a word that does not have a recognized definition. The correct term is "solstice," which refers to either of the two times of the year when the sun is at its highest or lowest point in the sky at noon, resulting in the longest or shortest day of the year.
