The Solstice occurs twice each year (around 21st June and 22nd December) as the Sun reaches its most northerly or southerly point relative to the equator. In the northern hemisphere, at the summer solstice the sun is directly overhead at 23.5 degrees North (the Tropic of Cancer) and the length of daylight is at its maximum, whilst at the winter solstice the sun is directly overhead at 23.5 degrees south (the Tropic of Capricorn) and the length of daylight is at its minimum. The apparent migration of the overhead sun gives rise to the autumnal and spring equinoxes, when the sun is overhead at the equator.
