Whether the full moon in September 2021 is a Harvest Moon or a Worm Moon is not rocket science to solve. I mean, it’s just simple physics. The ninth full moon of 2021 in the earth’s northern hemisphere is known as the Harvest Moon. This September full moon will occur on Monday, September 20, 2021, at sharp 19:54 at Eastern Standard Time (EST).
On the contrary, for the people living in the southern hemisphere; let’s say for Australian People, they call the full moon in September 2021 a Worm Moon. In earth’s southern areas, the worm moon will occur on Tuesday, September 21, at sharp 09:54 at Australian Eastern Standard Time (AEST).
Wanna know why different full moon names in the different hemispheres and many more interesting facts about the full moon in September 2021? I would recommend you to keep reading! Let’s dive right in!!!
Why Different Full Moon Names in Different Hemisphere?
Just because there is an approx 6 months of seasonal difference between the northern and southern hemispheres, people living above and below the equator use different full moon names.
Obviously, now you would be thinking that what could be the reason behind the seasonal difference between the two hemispheres?
Well, just because the earth has an axial tilt of 23.4 degrees, there is a seasonal mismatch between the southern and the northern hemisphere. See the above image for proper understanding.
However, If you wanna know more about the earth’s tilt and how it affects the seasons on the earth, you can check this article. I can bet you will love this piece of article.
Different Full Moon Names in Northern Hemisphere
For millennia, ancient humans have used different seasons as a guide to track the different full moon phases. Or, you can say for millennia, humans have used the full moon phases to track the changing season. However, seasons are not the only possible way to define different full moon names.
I mean the names given to the various full moon phases are based upon a couple of different sources. Out of all, the most famous and widely acknowledged full moon names come from the tribes of native American culture.
As per the legends, in order to keep track of changing seasons, the Algonquin tribal people used to follow the lunar calendar rather than following the solar calendar.
These full moon names were later adopted by Colonial Americans and European settlers. And, with time, these names were finally integrated with the modern (Georgian calendar) calendar.

Full Moon in September 2021 – Harvest Moon in Northern Hemisphere

Not to mention, this full moon will also be the last full moon before the occurrence of the September Equinox in the northern hemisphere. In 2021, September Equinox i.e the first day of fall in the northern hemisphere will occur on Wednesday, September 22, at sharp 19:21 Universal Time Coordinate (UTC).
Other Cultural Full Moon Names for September 2021 in Northern Hemisphere

Different Full Moon Names in Southern Hemisphere
You would be baffled to know that the full moon names used in the southern hemisphere are the same as the northern hemisphere, just the seasonal difference. Wanna know why???
Well, because most of the people living in the southern hemisphere (let’s say Australia or New Zealand) are none other than the European settlers.
In other words, one can say that European settlers, at first, integrated the native American full moon names into their modern Georgian calendar. And, later, many of these full moon names went with them to new places around the world.

Full Moon in September 2021 – Worm Moon in Southern Hemisphere
In the southern hemisphere, the full moon in September is known as the Worm Moon. WHY? Because this full moon marks the end of the winter season. Or, one could simply say that the cold weather starts to clear slightly in the earth’s southern areas.
Just to mention, this month’s full moon will also be the last full moon before the occurrence of the September Equinox. September Equinox i.e the first day of Spring in the southern hemisphere will occur on Thursday, September 23, at sharp 5:21 Australian Eastern Standard Time (AEST).
Other Cultural Full Moon Names for September 2021 in Southern Hemisphere
Well, if you go somewhere away from your native place, you will see that local indigenous people have their own indigenous full moon names. Sadly, that is not the case with the people living in the southern hemisphere.
Not to mention, for several days, I have been trying to get some detail regarding the full moon naming criteria for the Earth’s southern areas. But, I did not find any single piece of work related to that.
However, I did find one resource where it has been mentioned that the native people of the southern hemisphere (Māori People of New Zealand) didn’t assign a name to only the Full Moon phase of each month. Every night of the Moon had a name.
Therefore, as a result of these elaborated naming conditions, many in the Southern Hemisphere rely on the European-inspired Full Moon Names.
Just to let you know, one of my friends Retha Potgieter recently told me about the update on Full moon names in South Africa. Since September 2020, South Africa have their own unique full moon names.
As per the Centre for Astronomical Heritage (CfAH), in South Africa, the full moon in September is known as SPRING MOON. The Centre for Astronomical Heritage (CfAH) is a non-profit company working to protect South Africa’s astronomical heritage.
The Centre’s mission is to record, preserve, and disseminate information about, South Africa’s tangible and intangible astronomical heritage. I would request you to visit this website at least once. They are doing really nice work.
