Question

what is solar midnight?

Answer 1

Solar midnight is the time opposite to solarnoon, when the Sun is closest to the nadir, and the night is equidistant from dusk and dawn. Due to the advent of time zones, which regularize time across a range of meridians, and daylight saving time, it rarely coincides with 12 midnight on the clock.

Answer 2

Solar midnight is that time opposite of solar noon, when the sun is closest to nadir and the night is equidistant from dusk and dawn. Due to the advent of time zones, which make time identical across a range of meridians, and daylight saving time, it rarely coincides with midnight on a clock.
