1. Dates of New Moon

The table below shows the dates of New Moon for the years 2000 through 2018 (in the Gregorian calendar). The dates are valid for Universal Time and were calculated for the average motion of the Moon, so they may occasionally be off by one day for any location on Earth.

The first column shows the year number. The other columns show the days of the month when it is New Moon, for the months of which the month number is listed at the top of the column (01 = January, 02 = February, and so on). There are two columns per month, but often only one is used, and sometimes none at all.

Because 19 calendar years are almost exactly as long as 235 synodical months, this table can be used also for years before 2000 or after 2018. For this, you should add 19 to or subtract 19 from the year for which you want to know the dates until you've found a year between 2000 and 2018. For example, the dates for 1965 are the same as those for 1965 + 2*19 = 2003.

2. Dates of Full Moon

The table below provides dates of Full Moon, in the same way as was done above for New Moons.
