The Chinese Lunar Calendar is a solilunar calendar, consisting of months corresponding exactly to lunar cycles and years which stay more-or-less in sync with seasonal years. The structure of the calendar depends on the exact times of certain astronomical events, principally dark moons and winter solstices.

This software allows you to: (i) Display the current phase of the Moon. (ii) Calculate the phase of the Moon for any time in the past or future within a 9000-year period. (iii) Convert between dates in various calendars (three solar calendars, the Gregorian Calendar, the Julian Calendar and the Solar Liberalia Triday Calendar, and four lunar calendars, the Goddess Lunar Calendar, the Meyer-Palmen Solilunar Calendar, the Hermetic Lunar Week Calendar and the Lunar Liberalia Triday Calendar).
