The summer solstice occurs some time between June 20 and June 22. As seen from a geographic pole, the sun reaches its highest altitude of the year on the summer solstice. Therefore the summer solstice is the longest day of the year, and in turn the shortest night.
On the day after the summer solstice daylight begins to slowly decrease, while nighttime slowly increases. This happens until the fall equinox which occurs some time between September 21 and September 24, when the sun directly shines on the equator and the length of day and night is nearly equal.
