Sun Calculator calculates the time of official sunrise/sunset and civil sunrise/sunset
based on your location and local time. The period between civil sunrise and
official sunrise, together with the period between official sunset and civil sunset,
are called civil twilight. The sun is below the horizon, but its light is visible because it
illuminates the upper layers of the atmosphere. Due to diffused light and different
shades of color in the sky, civil twilight is ideal for portrait and landscape
photography.
