On which days do the equinox happen in India?
- A.21 March and 22 December
- B.21 June and 23 September
- C.21 June and 22 December
- D.21 March and 23 September
Correct answer
Explanation
The correct answer is D, 21 March and 23 September. On these two dates the noon sun is vertically overhead at the Equator, the circle of illumination passes through both poles, and day and night are of nearly equal length everywhere on the earth; 21 March is the spring or vernal equinox and 23 September the autumnal equinox. Options A, B and C are wrong because each of them contains a solstice date. On 21 June the sun is overhead at the Tropic of Cancer, giving the longest day in the northern hemisphere, and on 22 December it is overhead at the Tropic of Capricorn, giving the shortest day in the north. The word equinox itself comes from equal night, which is the simplest way to separate the two equinoxes from the two solstices.
