Full Moon March 2025 – Worm Moon And Alternative Names
Why is March's full moon called the Full Worm Moon?
The March full Moon has one of the most unexpected names—the “Worm Moon.” Full Moon names often showcase seasonal highlights, such as May’s “Flower Moon” or September’s “Harvest Moon” or even animals common to each season, such as July’s “Buck Moon” or August’s “Sturgeon Moon.” But worms? Why do these invertebrates matter so much in March?

Full Moon Dates, Times, And Names
Why Is The March Full Moon The “Worm” Moon?
The “Worm Moon” got its name because in March the soil begins to warm and the very first signs of life begin to return as earthworms, beetle larvae, and grubs emerge from their winter dormancy. These invertebrates are some of the very earliest spring food sources for birds and animals, including bears, skunks, and other animals emerging from hibernation. The castings (vermicasts, waste from earthworms) left behind enrich the soil and make it possible to begin planting and gardening after winter’s end.
More March Moon Names
March has a wide variety of names for the full Moon because there are many different things happening as winter ends and spring begins. Names vary depending on their origins from ancient cultures or Native American tribes, regional climates, geography, and even individual dialects.
Many northern cultures have end-of-winter names for the March full Moon, such as the “Snow Crust Moon” or “Hard Crust on the Snow Moon” from the Ojibwe and Chippewa tribes near the Great Lakes. During March, deep snow thaws during warm days but refreezes during cold nights, creating a brittle crust on top of the snow.
Another late-winter name for the March full Moon is the “Sore Eye Moon.” This is common among several Native American peoples, including the Sioux, Lakota, and Assiniboine of the Great Plains, northern plains, and Dakotas. In these areas, bright sunlight of the late winter and early spring reflects off remaining snow, creating snow blindness or eye soreness.
As the weather shifts into early spring, strong winds are common as air temperatures rise. The Choctaw and Cherokee of the southeastern US, as well as the Catawba of South Carolina, call the March full Moon the “Wind Moon” because of this. Similar names are found in Celtic culture with “Moon of Winds.” In desert areas of the southwestern US, the March full Moon is the “Moon of the Whispering Wind” from the Hopi, or the “Little Sand Storm Moon” from the Zuni tribe.
“Spring Moon” is a more generic term occasionally applied to the full Moon in March, particularly with the Inupiat in Alaska and the Passamaquoddy of the northeastern US, while the Creek of the southeast use “Little Spring Moon” as a general description. Some cultures also recognize specific aspects of spring with the monthly name, such as “Moon When the Leaves Break Forth” from the Pueblo peoples of the southwest.
One critical aspect of spring food is when sap rises in trees, permitting sap collection to make maple syrup and maple sugar. The Ojibwe of southern Canada call the March full Moon the “Sugar-Making Moon” to note that importance, and likewise, the Shawnee of Ohio and Pennsylvania use the term “Sap Moon” this month.
In more southerly areas where spring may arrive in very early March the name “Strawberry Moon” may be used this month, which is one name the Catawba tribe of South Carolina and the Cherokee of North Carolina occasionally use. This is more often reserved for June’s full Moon, however, when the appearance of wild strawberries is much more widespread.
Animal Names for the March Full Moon
Not all names for the full Moon of March are based on seasonal weather patterns or plants. Several cultures use animal names, such as the “Crow Moon” to note the cawing of crows as they seek spring mates and define their territories after winter ends. This is a common March Moon name among the Ojibwe of southern Canada.
Seasonal animal patterns also contribute to Moon names. The Arapaho, whose livelihood revolved around the movements and lifespan of the buffalo, call the March full Moon the “Buffalo Dropping Their Calves Moon” to note the spring birthing season.
Just as many animals rely on the “Worm Moon” as an early food source, some tribes also noted spring food sources in different names for the March full Moon. The Algonquin of the Great Lakes region use the name “Catching Fish Moon” since fish are one of the most plentiful food sources in early spring before plants begin to grow and when other hunting remains scarce. This was also a common name used by American colonists.

Unexpected March Full Moon Names
There are some even more unexpected names for this month’s full Moon than the “Worm Moon.” Because seasons and plant cycles are vastly different in the southern hemisphere, names south of the equator would naturally vary. “Corn Moon” and “Harvest Moon” are common names for the March full Moon in South Africa and other southern hemisphere regions.
The “Chaste Moon” is another unique option for the March full Moon. This name is used in neo-Pagan circles and refers to the purity of the season as life renews after winter. The “Chaste Moon” was also a common name in medieval English.
With so many options of what to call the March full Moon, there is a name to suit every culture, interest, and region as the Moon reaches its peak in the third month.

I’m confused. Earthworms disappeared from most of North America after the last ice age. The earthworms of North America are not native. They are from Europe, and were brought by settlers within the past few hundred years. So did the Natives really call it the Worm Moon, or did the translation just get it wrong?
I would like to call the March full moon simply “The Spring Moon”.
Amazing words descriptive too
Worm casts and robins?
Enjoyed my first news letter would like to know if this moon is also for worming children or adults if not is it the new moon would like to know.
Hi Cora McPhee, there is no relationship with this full Moon to deworming. It’s just the name of the Moon given by Native Americans due to springtime. We don’t offer a “best day” task for this.
Any full moon is the best time
Go to the Best Days section of the Farmers Almanac and you can find the Best Days to plant seeds. You can also find the section you live in and the best days for planting in your area as well.
If you want to know about the moon stay up late and go outside.
I love the little obscure facts that you publish in this Farmers Almanac newsletter, such as the names of moons and other such interesting bits of knowledge.
I want to start planting flower seeds and plants. When would be the best time to start.

The full worm moon is the indication to start planting seeds indoors 6-8 weeks before last frost should be right now, but the sap isn’t running yet because of the cold winter, does this mean that sowing seeds around now (March 17) should be postponed a couple of weeks to coincide with the sap? Is the sap a good indication?
That really depends on where you live, Laura Knox. Talk to someone at your local greenhouse or agricultural extension office.
Planting on moon cycles
Information on planting during a full worm moon.
I want to plant vegetable seeds and plant. I understand things grown under the ground, i.e. carrots, beets, should be planted during the dark of the moon. Things that grow above the ground. i.e. tomatoes, corn, etc. should be planted in the light of the moon. How can I find out when these times are or how they are identified on this website.
