Question

What will be the duration of daylight on March 21st at 23°30'N and 66°30'S latitudes? Give reason.

Answer 1

On March 21st, which is the Vernal Equinox, the duration of daylight at 23°30'N and 66°30'S latitudes will be 12 hours.

Reason: During the equinox, the Sun is directly above the Equator. This results in equal day and night durations (12 hours each) everywhere on Earth, regardless of the specific latitude. The tilt of the Earth's axis does not affect this equality on the equinox, so all locations experience the same amount of daylight.
