PHASES OF THE MOON: 2001 TO 2100 - NASA

The following table gives the date and time (Universal Time) of all phases of the Moon for a period of one century. This data is provided primarily to assist in historical research projects. For the year 2000, the length of the mean synodic month (New Moon to New Moon) is 29.530588 days (=29d12h44m03s). However, the length of any one synodic month can vary from 29.26 to 29.80 days due to perturbing effects of the Sun on the Moon's eccentric orbit.

The phase table also indicates whether an eclipse of the Sun or Moon occurs on the date in question and gives the eclipse type. An eclipse of the Sun can occur only at New Moon, while an eclipse of the Moon can occur only at Full Moon. In any calendar year there are a minimum of two solar and two lunar eclipses. The maximum number of eclipses in any one year is 7 (4 solar and 3 lunar, or 5 solar and 2 lunar). The following table lists abbreviations for the different types of solar and lunar eclipses.

The table can be viewed HERE.

Thanks to NASA for this valuable information!
