SolarCalc is a utility to calculate sun and moon rise and set times at your current location. SolarCalc will also display lunar phase dates as well as the Julian Day, Greenwich Universal Time, Greenwich Sidereal Time and Terrestrial Dynamical Time.

Display's Civil, Nautical, and Astronomical twilight times.
Displays Sun and Moon Right Ascension and Declination.
Displays Sun and Moon Altitude and Azimuth.
Display's Moon age, distance and apparent size.

Note: SolarCalc accounts for approximate refraction of 0.5667 degrees. Rise or Set is based on the upper limb instead of the center of the disc. Civil twilight calculations are based on the zenith distance of the center of the solar disc (6 degrees below the horizon).
