Traditional Full Moon Names

Where These Names Actually Come From

Most of what's published online about traditional full-moon names traces to the Maine Farmers' Almanac, which began publishing lists of names it attributed to Algonquin-speaking peoples of the northeastern United States starting in the 1930s, as a reader feature. That attribution is genuine in the sense that many of these names do trace to real Indigenous naming traditions — but it's a 20th-century popularization that compressed a much wider range of distinct naming systems, developed independently by different nations across a huge geographic range, into one tidy monthly list. Each page below states that history honestly, including the real alternate regional and European names several months also carry, and where sources genuinely disagree on a name's origin rather than presenting one tidy story as settled fact.

Twelve Fixed Months, Plus Two That Break the Pattern

Twelve of the thirteen entries below map to a fixed calendar month, from January's Wolf Moon through December's Cold Moon. The Harvest Moon is the outlier: rather than owning a set month, it goes to whichever September or October full moon actually lands closest to the autumn equinox that year, bumping the usual Corn Moon or Hunter's Moon name aside for the occasion. Blue Moon is a different kind of outlier again — not a monthly name at all, but the label for a second full moon squeezing into one calendar month, explained on its own dedicated entry below.

Each name's page covers its documented origin, genuine alternate names from other regional and European traditions, what's actually happening in the sky that month, and honest answers to the questions people most often ask about it. For the exact date, time, and zodiac sign a specific name's next occurrence actually falls on, see our full-moon calendar, which computes each occurrence individually rather than estimating from the name alone.

The Names With Deeper, Disputed Histories

A few of these names have more layered history than a single sentence can capture. Blue Moon carries a documented case of a 20th-century magazine error becoming today's dominant popular definition, alongside an older, still-valid seasonal definition most casual sources never mention. Harvest Moon isn't tied to a fixed month at all — it's defined by proximity to the autumn equinox, and comes with a real, observable moonrise-timing effect (a shortened gap between successive nights' moonrise) that you can actually watch for yourself rather than take on faith. Worm Moon carries a genuinely disputed origin story — sources disagree on whether it refers to earthworm casts or beetle larvae — and we say so plainly rather than picking one to sound more authoritative.

Several names also carry real biological or ecological detail worth knowing beyond the naming tradition itself: Buck Moon's antler-regrowth explanation is genuine, documented deer biology; Sturgeon Moon's namesake fish can live well over a century; and Beaver Moon sits at the intersection of animal behavior and a documented historical economic activity, the North American fur trade. Each entry below separates that kind of checkable fact from the parts of its story that remain genuine folklore.

Reading Through All Thirteen

Twelve of these thirteen entries map to a fixed calendar month; the Harvest Moon breaks that pattern by design, defined by proximity to the autumn equinox rather than a specific month, and the Blue Moon isn't tied to any month at all — it's whichever full moon happens to be the second one within a single calendar month. Reading through all thirteen in order gives a genuine sense of how a single naming tradition, developed piecemeal across different regions and centuries, ended up covering the entire year.

Start with whichever name brought you here, or read straight through the list below in calendar order — January's Wolf Moon through December's Cold Moon, with the Harvest Moon and Blue Moon as the two names that break the fixed-month pattern entirely.

One thread worth tracing across several entries: which activity (hunting, fishing, planting, trapping) left its mark on a given month's name says something real about what mattered most to the communities that coined it, at that specific point in the agricultural and hunting calendar — a small window into pre-industrial seasonal life, independent of whether you have any interest in the Moon itself.
