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.
Moon and Sun positions are computed using JPL ephemerides (DE440).
east longitude and latitude of the observer can be found in:
local time - universal time is available here (daylight saving time is considered):
