Frequently Asked Questions
When are the full moons in 2027?
The table above lists all 12 full moons of 2027 with exact UTC dates and times. Full moons recur every 29.53 days on average, so each one lands about a month apart.
How many full moons are there in 2027?
12. 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.
Is there a blue moon in 2027?
No. Every month of 2027 (UTC) holds exactly one full moon, and the monthly blue moon rule needs two in the same calendar month.
What is the Harvest Moon in 2027?
The Harvest Moon is the full moon closest to the September equinox. In 2027 that is the moon of 15 September 2027. Around it, moonrise times cluster close together on successive evenings, which is what gave the moon its farming name.
Why are the full moon times listed in UTC?
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.
Are the traditional full moon names official?
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.
