In the Northern Hemisphere, the summer solstice occurs sometime between June 20 and June 22.
The mid-year solstice denotes the moment that the Sun arrives at its most noteworthy point overhead. This is the longest day of the year, and the days gradually get shorter after that until the winter solstice, which is on December 21. The winter solstice, which marks the shortest day of the year, occurs in the Southern Hemisphere at the same time as the summer solstice in the Northern Hemisphere. In the Northern Half of the globe, the summer solstice happens at some point between June 20 and June 22, and between December 20 and December 23 in the Southern Hemisphere.
