Description

The cycle of [/phases phases], as seen from Earth, from one (geocentric) New Moon to the next.

Additional Information

  • The length of the cycle is said to vary from about 29.27 to 29.83 (Earth) days, with an average of 29.530589 days.
  • Lunations are sometimes numbered from an arbitrary starting point. The most popular system seems to that of [/Brown E. W. Brown] who counted the lunation commencing with the New Moon of January 17, 1923 as "1".
