Solstice: the time or date (twice each year) at which the sun reaches its maximum or minimum declination, marked by the longest and shortest days (about June 21 and December 22).
Oxford Dictionary
The word solstice has its origin from the Latin word solstitium “point at which the sun seems to stand still.”
So here you have it. Summer…..
And Winter….
