Answer:
Marking the beginning of spring, the sun will cross the plane of the earth's equator on Monday morning, making day and night of approximately the same duration. The event, known as equinox, is eagerly awaited by space enthusiasts as it takes place only twice a year, on March 21 and September 23.

Answer:
On 21st March, direct rays of the sun fall on the equator. At this position, neither of the poles is tilted towards the sun; so, the whole earth experiences equal days and equal nights.
