Question

What are the two equinoxes? Give their dates in each hemisphere.

Answer 1

• The two equinoxes are the times when the noon sun is directly overhead at the equator, resulting in equal lengths of day and night all over the earth.
• These occur twice a year around 22nd March and 23rd September.
• In the northern hemisphere, 22nd March is known as the spring equinox (or vernal equinox), while 23rd September is the autumnal equinox.
• Conversely, in the southern hemisphere, 22nd March is the autumnal equinox, and 23rd September is the spring equinox.
• On these days, both hemispheres experience moderate temperatures with equal day and night durations.
