USNO astronomical data (Sun, Moon, eclipses, seasons)

Astronomical data computed on request by the US Naval Observatory's Astronomical Applications Department (aa.usno.navy.mil API v4): sunrise, sunset, solar noon and civil twilight, moonrise, moonset and Moon phase with illumination for any place and date from 1700 to 2100; primary Moon phase dates and times (new, first quarter, full, last quarter); the solar eclipses of any year from 1800 to 2050 and what a given location sees during one (1996 to 2026); and equinox, solstice, perihelion and aphelion times. US government work, public domain.
