What time is twilight?

Answer 1

Twilight is the time between dawn and sunrise, and the time between sunset and dusk. Sunlight scattered in the upper atmosphere illuminates the lower atmosphere, and the surface of the Earth is not completely lit or completely dark. The sun itself is not actually visible because it is below the horizon

Answer 2

=The time given for twilight/dawn, as used by most planetarium operators, beginning when the first light of the sun lights the sky and ends when the upper limb (edge) of the sun clears the horizon. (dawn). This is the accepted point of sunrise. Sunrise then lasts until the bottom of the sun clears the horizon. Just the opposite for twilight. Sunset when the lower edge of sun touches horizon, start of twilight when the top edge disappears behind the horizon. This is the point that twilight starts. These times can vary depending up latitude. But by definition, that never changes.=
