When is Twilight?

Question

I googled it and it says ‘before sunrise and after sunset’ but I don’t understand how that makes sense because one is AM and the other is PM

In: 1

Answer 1

Twilight is when the sun is below the horizon but the ground is lit from its light scattered in the the atmosphere. The higher parts of the air can see the sun at that point. In the evening twilight happens after sunset, and in the morning before, although I rarely hear this word used in the latter case. Twilight is longer near the Earth’s poles than around the equator because the planet’s rotation makes the sun appear to descend at a more level path.
