Full Moon for March 2018

March Full Sap Moon & Blue Moon

Full Sap Moon - OFA

On Saturday evening, March 31, the Full Sap Moon rises! This is the second full Moon of the month—a Blue Moon. Get ready to enjoy this March marvel.

March Full Moon Names

The Full Worm Moon

In March, we traditionally have one full Moon—the Full Worm Moon—which was traditionally called the Full Worm Moon by Native Americans who used lunar phases to track the seasons. Colonial Americans also used these names, especially those of the local Algonquin tribes who lived between New England and Lake Superior.

At the time of this Moon, the ground begins to soften enough for earthworm casts to reappear, inviting the return of robins and migrating birds—a true sign of spring. Roots start to push their way up through the soil, and the Earth experiences a re-birth as it awakens from its winter slumber.

The Full Sap Moon

There are many alternative names for the March Moon, depending on the Native American tribe and region. One alternative name is the Full Sap Moon, as this is the time of year when the sap of sugar maples starts to flow.

So, we are calling this second full Moon in March the “Full Sap Moon.”

See all Full Moon names and their meanings.

What’s a Blue Moon?

Some folks are calling this second full Moon the “Blue Sap Moon.”  Yes, we know, people love to give Moons names! We explain …

When two full Moons occur in a single calendar month, the second full Moon is called a Blue Moon.

This isn’t the first Blue Moon we’ve seen in 2018. Remember the Super Blue Blood Moon on January 31st? 

Now it IS unusual to have Blue Moons happen twice in one year. We won’t see it happen again until 2037.

Moon phases

Before going to the dentist for any work, check the date of your appt to see what part of the body the moon sign is in. If in the head, do not have dental work done, it will not take... This has happened to me SEVERAL times and now I tell everyone who's going to the dentist!

Full Moons for March.

I was a missionary to Mexico for seven years and was amazed to learn and to also witness the farmers go by the moon to plant the seed in the spring.They kept an eye on the moon also to castrate the young male...now I don't recall how the moon looked when they could not castrate because either calf would bleed and or not bleed depending,I saw it worked everytime! Same thing happened when they put a post in the ground when fencing their fields! I learned so much how following the moon worked for these people that lived in desert mountains worked for them,I find myself going by the moon in my life, I follow farmers almanac.Sylvia Mendoza

Cutting hair by the moon

My Dad use to tell me this about the moon when I was young, like when to slaughter hogs, trimming the hedge. I also noticed as I got older that sometimes after a haircut it seemed to grow so fast and other times not so fast. Now I try to schedule my haircuts by the moon. Is there any validity to things thinking?


I have been getting my hair cut for years now with and without a full moon. Still have the same bald spot!

The Moons

I Love looking at the Full Moon when we have one - now I'll check when we have the next one. Thanks for the info from The Farmer's Almanac - love the recipes

not much

hi thanks for a relly informative page

It drives me crazy seeing all

It drives me crazy seeing all these websites saying that the Full Moon is called either the Worm Moon or the Crow Moon. No body knows how to research. So let me educate you all. The Full Moon is called the STORM MOON. It is called that because of the seasonal storms to come.

The Full Moon Names we use in

The Full Moon Names we use in the Almanac come from the Algonquin tribes who lived in regions from New England to Lake Superior. They are the names the Colonial Americans adapted most. Note that each full Moon name was applied to the entire lunar month in which it occurred. It might interest you that the August Full Moon has been called the Storm Moon in the Southern Hemisphere.

It drives me crazy hearing

It drives me crazy hearing people think that they know everything and just because someone has something different to say they must be wrong. The farmer's almanac has been around since Christ was a carpenter and have used these terms all that time. You may have different terms but they are using Algonquin terms which have probably been around longer than whoever made up your terms.

hello, The answer you are

The answer you are looking for is before the story of "Christ". The correct name for the full moon of March is the Chaste Moon. Your welcome.
Blessed Be!

The Farmers Almanac will

The Farmers Almanac will refer to the March full moon as names adapted from the northern Native American tribes because that is when snd where The Farmers Almanac was published. It hasnt been around since "Christ", it's been around since George Washington. It was published by Benjamin Franklin first as Poor Richard's Almanac and has been a seasonal go-to ever since. Of course Im sure there are many other religions and regions around the world that have the same concept of an almanac and have probably been around for way longer. But "The Farmer's Almanac" is only around 300 years old. Also the moon has many names :) so dont be upset when people refer to it by it's regional name. In many northern areas, this is what it's known by.

I must say I did get a chuckle about planting of crops, at least here in the North East, there is way to much snow, and we have had such cold weather that the ground is still frozen beneath the 2' of snow on the ground.

Planting days are also good

Planting days are also good for any "fertile" activity. I.E. if you are trying to land a new job, see if you can't get your interview planned for a planting day ;)
