what are the seasons in the northern and the southern hemispheres on 23rd September

Answer 1

The vernal, or spring, equinox falls on March 20 or 21, and the autumnal equinox is on September 22 or 23. The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere.

Answer 2

1) On to days of the year 21st March and September 23rd, rays of the sun fall directly on the equator.
2 ) The earth experiences equal days and nights since none of the poles is tilted towards the sun which is called an equinox.
3) The Northern Hemisphere faces the autumn season on 23rd September.
4) The spring season is present in the Southern Hemisphere at the same time.
5) In case of 21st March the seasons are reversed accordingly.
6) This explains the reversal of seasons between the two dates.
