The summer solstice is the longest day of the year, when the sun is at its most northern position (June 21st). The winter solstice is the shortest day of the year, when the sun is at its most southern position (Dec. 21st). The equinoxes are days when the sun is exactly in the middle of the ecliptic so day and night are close to being equal. ................
