Why are days and nights equal at all places on earth on September 23?

उत्तर
Days and nights are equal at all places on Earth on 23 September because it is the Autumnal Equinox. On this day, the Earth's axis is not tilted towards or away from the Sun, so the Sun is directly above the Equator, resulting in equal durations of day and night all over the planet.
