Year, month, day, lambda (Geographic east longitude of the observer in [deg]), phi (Geographic latitude of the observer in [deg]), zone (local time - universal time in [h]), and twilight (Indicates civil, nautical or astronomical twilight) are received, then rising and setting times of the Sun and the Moon and twilight times are computed.
The positions of the Sun and the Moon are computed using Jet Propulsion Laboratory Development Ephemeris (DE440).
