Frequently asked questions
What is a moon calendar?
A moon calendar shows the phase of the Moon and the zodiac sign it occupies for every day. Astrologically the Moon changes sign every 2-3 days and completes a full cycle from new moon to new moon in about 29.5 days - the basis of the lunar rhythm.
When are the next new moon and full moon?
The exact dates for the current month are highlighted in the calendar above, together with the sign in which they occur. The data is recalculated automatically for every new month.
What is the moon phase used for?
The waxing Moon (new moon to full moon) is traditionally linked with beginnings, growth and accumulation, while the waning Moon is linked with completion, release and clearing. The full moon brings culmination and clarity; the new moon brings a fresh start.
How is the data calculated?
Positions of the Sun and Moon are computed from astronomical ephemerides based on JPL DE431, accurate to better than 0.01°, in geocentric ecliptic coordinates - the same standard we use for natal charts.
