A lunation lasts 29.53 days, so twelve of them leave about eleven days of the year spare — enough for a thirteenth full moon in roughly three years out of eight.

Columns

phase New Moon, First Quarter, Full Moon or Last Quarter
utc Moment of the phase, UTC, to the minute
moon_sign Tropical zodiac sign of the Moon at that moment
moon_degree Degree within that sign
eclipse Solar or lunar if the phase coincides with an eclipse, otherwise empty

How it was computed

The principal periodic terms of the Moon’s longitude (Meeus, chapter 47) set against the solar longitude; a phase is the moment the elongation reaches 0°, 90°, 180° or 270°, found by bisection. Eclipse flags mark syzygies close enough to a lunar node.

How it was checked

New and full moons fall within about 20 minutes of published times, and the eclipse flags were checked against the published eclipses of 2024–2030.
