- “Worm moon”
- “Crust moon”
- “Sap moon”
The moon will be completely full at 6:49pm GMT. This third full moon of the year was important to many historic cultures and bore many names. Traditionally, the “Crow moon” is the full moon of March, and the last full moon of the winter. The name “Crow moon” indicates the return of crows after the long cold season.
Likewise the name “Worm moon” indicates the return of worms to the warming earth. Further to the north, the term “Crust moon” was used to indicate the type of snow common in the Spring — which featured an icy crust on top from melting and refreezing.
The term “Sap moon” was used by American settlers to indicate the time of year when maple sap would begin to flow again.
April 12th: New Moon

April 27th: Full moon, Supermoon
Folk names for the April full moon:
- “Pink moon”
- “Egg moon”
This full moon will be the first of three “supermoons” in 2021. It will be full at 3:33am GMT. This full moon will appear larger than other full moons, relative to its position in the sky, because the full moon coincides with the Moon’s perigee.
DEFINITION: When the moon is full at the same moment the moon is at perigee or closest to the earth in its orbit, it’s called a “supermoon”. Supermoons appear larger because they are closer closer to the Earth during the full moon phase.
The April full moon was also called a “pink moon” by the Algonquin tribes of North America and by colonial settlers because of the pink flowers (wild ground phlox) which would appear at this time of the Spring, and seem to glow under the light of the full moon.
Other North American tribes referred to the April moon as the “egg moon” because it coincided with birds nesting and laying eggs after the long winter.

The new moon phase will begin at 10:54am GMT and will be invisible in the night sky.
Wondering what today’s moon phase is? Here’s a fast way to look up the moon phase for any date.
May 26th: Full Moon, Supermoon
Folk names for the May full moon:
- “Milk moon”
- “Flower moon”
- “Corn moon”
- “Hare’s moon”
The second supermoon of 2021 will occur at 11:14am GMT. Because the moon will be full during its perigee (the point of its orbit where it is closest to the earth) it will appear larger than normal in the sky.
The May full moon is also known as the “milk moon” in English and European cultures. The May full moon is called the “milk moon” is because cows would graze on fresh Spring grasses and flowers and begin to produce their best milk at this time of the year. The term “Flower moon” was used by Algonquin tribes because of the wildflowers which would bloom in May.
The term “Corn moon” was used by several Native American tribes because the May full moon indicated the best time to harvest corn.
Lastly, the term “Hare’s moon” dates back to pagan times, when it was thought that the image of a hare could be seen among the craters of the moon. This observation is similar to the East Asian term “Rabbit moon” which also saw the pattern of moon craters as resembling a rabbit.
May 26th: Total Lunar Eclipse, “Supermoon Eclipse”
On May 26th the moon will pass entirely within the earth’s shadow or umbra. This will happen on the same day that the moon is at perigee or closest to the earth.
When the moon passes into the umbra of the earth, it takes on a reddish hue, and is usually still visible in the sky.
The lunar eclipse will be visible in the Pacific hemisphere, and viewable from Japan, Australia and the Western United States.

- “Strawberry moon”
- “Rose moon”
June 24th marks the third supermoon of 2021. The moon will be full at 6:41pm GMT and will appear larger in the sky because it full at the moment of perigee, or the point it its orbit where the moon is closest to the earth.
The moon was called a “honey moon”, like the term honeymoon, by Europeans due to the custom of young couples getting married in the month of June. The term ‘honeymoon’ comes from the “honey moon”, or June full moon, and refers to the month of time spent together after the wedding.

August 22nd: Full Moon, Blue Moon
Folk names for this moon: (None. On a blue moon, the folk names are transferred to the fourth full moon of the season)
The third of four full moons this season will begin at 12:02pm GMT. This full moon is a rare blue moon, which happens every two to three years. See the blue moon definition below:
DEFINITION: A “blue moon” is an extra full moon which occurs in a single season. Typically there are 3 full moons in each of the year’s four seasons, with the third lunar cycle in each season marking the end of that season. But if a fourth full moon occurs in any season, the preceding (third) full moon is called a “blue moon” in order to prevent the season from ending early. In these cases, the season ends after the fourth moon cycle. Blue moons are rare events, occurring once every 2 to 3 years — hence the expression: “Once in a blue moon“. The term “blue moon” has nothing to do with the color of the moon. Proper names and folk names for a blue full moon are transferred to the fourth and final full moon of the season, hence a blue moon has no folk names. It is just a “blue moon”.
September 7th: New Moon
The September new moon will begin at 12:52am GMT marking the darkest point in the lunar cycle.
September 20th: Full Moon
Folk names for this moon:

October’s full moon phase will begin at 2:57pm on October 20th. The names “Hunters’ moon” and “Blood moon” both reference the annual autumn hunting season, when deer and other animals are fat and prime for hunting.
The term “Travel moon” was similarly used by Native Americans to describe the time when hunters would track migrating herds of animals over great distances. Other Native American tribes refer to the October moon as the “Dying grass moon”, as the green grasses of summer fade away to the tans and browns of the fall and winter season.
