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 [hour]) and twilight (Indicates civil, nautical or astronomical twilight) are received, then rising and setting times of the Moon and the Sun and twilight times are computed.
Positions of the Sun and the Moon are computed using Jet Propulsion Laboratory Development Ephemeris (DE440).
east longitude and latitude of the observer can be found in:
local time - universal time is available here (daylight saving time is considered):
