What moon is on March 2023?

The Full Worm Moon of March 7, 2023 takes place after midnight. This chart shows the almost full moon near Regulus and Denebola in Leo the Lion on the evening of March 6, 2023.

The full moon on March 6-7, 2023, is the closest full moon to the March equinox.

March full moon

When to watch in 2023: Nights of March 6 and 7.
Where to look: Look for the bright round moon in the east in the evening, overhead around midnight, west before sunrise.
Crest of the full moon falls at 12:42 UTC on March 7, 2023. That’s 6:42 a.m. CST in central North America. So if you live in central North America, your fullest moon will come around dawn on March 7, 2023.

All full moons rise in the east at sunset, and set in the west at sunrise. They are visible all night. At full moon, the sun, Earth and moon are aligned in space, with the Earth in the middle. The moon’s day side – its fully lighted hemisphere, faces us. That’s why the moon looks full. Note that the moon will look full and round for a day or two around full moon. This March 6-7, 2023 full moon is the closest full moon to the March equinox, which happen on March 20, 2023.

It’s the Worm Moon

All the full moons have names. Popular names for the March full moon are Worm Moon, Crow Moon and Sap Moon.The name Worm Moon honors the stirring of earthworms and insect larvae in the slowly warming late winter and early spring soil.

Opposite a Harvest Moon

The March 6-7 full moon is the closest full moon to 2023’s March equinox, which will fall at 21:24 UTC on March 20. It’s the spring equinox for the Northern Hemisphere. And it’s the autumn equinox for the Southern Hemisphere. So for us in the Northern Hemisphere, the March full moon shows characteristics opposite those of a Harvest Moon. Meanwhile, in the Southern Hemisphere, this full moon has all the Harvest Moon characteristics.

Harvest Moon characteristics. We in the Northern Hemisphere use the term Harvest Moon for the full moon nearest the autumn equinox (the Southern Hemisphere doesn’t have this same tradition of full moon names). All full moons rise at or around sunset. And – because the moon moves eastward in orbit – the moon typically rises about 50 minutes later with each passing day. But, around the time of the Harvest Moon, the lag time between successive moonrises is reduced to a yearly minimum. For instance, at and around 40 degrees south latitude – around the time of the March full moon – the moon rises only about 30 to 35 minutes later daily. The short time between successive moonrises continues for several days. So – around the time of the autumn equinox, and the Harvest Moon – there’s a bright full-looking moon in the early evening sky for several evenings in a row.

March full moon characteristics. In the Northern Hemisphere, this March full moon is the closest full moon to our spring equinox. So the lag time between successive moonrises reaches a yearly maximum. For instance, at 40 degrees north latitude, the moon rises some 75 minutes later from one day to the next, around the time of full moon. The longer-than-usual time between successive moonrises continues for several days. So – around the time of the spring equinox and the March full moon – there’s a longer-than-usual period of darkness (no moon) in early evening, for several days in a row following the date of full moon.

Arc of March full moon

And it’s not just moonrise times. It’s also the height of the moon’s arc across our sky that varies from month to month, and season to season. Every full moon rises in the east, as the sun sets in the west. Every full moon arcs across the sky throughout the night, and sets around dawn. For us in the Northern Hemisphere, the arc of this March full moon is lower than the paths of the full moons of December, January and February.

For those in the Southern Hemisphere, the full moon’s arc across the sky is climbing higher with each successive month, and will continue to do so until around the June solstice.

Before the advent of artificial lighting, our ancestors must have been well aware of these seasonal vagaries of our wayward moon.

March full moon in Leo

As seen from the Americas, the full moon on the night of March 6-7, 2023, is located in the direction of the constellation Leo. It glows between Leo’s brightest star, Regulus – said to represent the Heart of the Lion – and the star Denebola, in the Tail of the Lion. Denebola is the western member of the asterism called the Spring Triangle.

March full moons and the equinox

The March full moon sometimes sets the date of Easter Sunday, but not in 2023. In 2023, we have a full moon in early March, and another full moon in early April. Easter comes on the first Sunday, following the full moon, after the March equinox. So the April full moon – on the night of April 5-6, 2023 – sets the date of Easter Sunday (April 9, 2023).

Bottom line: We in the Americas will see the moon as most full on the night of March 6-7, 2023.
