Answer» March 21 and September 23 are called equinoxes. The apparent position of the sun on these days will be over equator. Hence the length of day and night will be equal on these days in both the hemispheres. On June 21, known as summer solstice, the sun will be vertically above the Tropic of Cancer. This is the longest day and the shortest night in the Northern Hemisphere. On December 22, known as winter solstice, the sun will be vertically above the Tropic of Capricorn. This is the longest night and the shortest day in the Northern Hemisphere.
