Full Moon Calendar 2028: Dates, Times, and Names

The table above lists all 13 full moons of 2028 with exact UTC dates and times. Full moons recur every 29.53 days on average, so each one lands about a month apart, and 31 December 2028 carries the month’s second full moon — a Blue Moon.

13. A calendar year holds 12 or 13 full moons because 12 lunations last about 354 days, roughly 11 days short of the calendar year — the surplus adds up to a 13th full moon every two to three years.

Yes. 31 December 2028 is the second full moon of that UTC calendar month — the monthly Blue Moon. (An older, seasonal definition counts the third full moon of a season with four; the monthly rule is the one most calendars use today.)

The Harvest Moon is the full moon closest to the September equinox. In 2028 that is the moon of 3 October 2028 — an October Harvest Moon, which happens when October’s full moon falls nearer the equinox than September’s. Around it, moonrise times cluster close together on successive evenings, which is what gave the moon its farming name.

A full moon is a single instant, and UTC is the unambiguous reference for it. Your local time differs by your timezone offset, and when the instant falls near midnight the calendar date can shift by one day between countries — which is why almanacs in different places sometimes print different full-moon dates.

No — names like Wolf Moon, Strawberry Moon, and Cold Moon come from folk tradition, best known today through the Farmers’ Almanac list. Different cultures use entirely different names. This calendar indexes the names by the UTC month in which each full moon falls, which is the convention most English-language almanacs use.
