Evening is usually defined as the time between afternoon and you go to bed while night is defined as the period between sunset and sunrise. The time that evening begins is arguable but according to the Oxford English Dictionary it is at 6:00 p.m. Another definition claims that evening ends and night begins after sunset. An exact answer would be the following: Evening begins at 6:00 p.m. and ends at dusk when no sunlight is visible. The time from sunset, when the sun sinks below the horizon, until dusk is called twilight. Night begins at dusk and lasts until dawn, when sunlight is first seen.
