Ready for a change of season? The March Equinox will occur on Sunday, March 20th this year, marking the beginning of spring in the northern hemisphere and fall in the southern hemisphere. The exact time is 23:21 (or 11:21 p.m.) at Coordinated Universal Time (UTC), which is 4:21 p.m. Pacific Daylight Time, 7:21 p.m. Eastern Daylight Time).
“Equinox” means “equal night” in Latin and, twice a year (in March and September), the sun shines directly on the equator, and the length of day and night are nearly equal in all parts of the world.
In addition, the full moon that heralds the Equinox on the night of March 19th will appear especially large and bright, due to its closer-than-usual relation to Earth. This supermoon, or perigee moon, is due to rise in the east and be the biggest in almost 20 years. If you are blessed with clear skies tonight, you will probably want to have a look.
The Farmers Almanac calls the March full moon the Full Worm Moon and notes: “As the temperature begins to warm and the ground begins to thaw, earthworm casts appear, heralding the return of the robins.”
Northern Native American tribes knew this moon as the Full Crow Moon, when the cawing of crows signaled the end of winter. They also used Full Crust Moon because the snow cover became crusted from thawing by day and freezing at night.
The Dakota Sioux named it the especially poetic Moon When Eyes Are Sore From Bright Snow. The Full Sap Moon, marking the time of tapping maple trees, is a Colonial American variation. More than one other culture calls it the Windy Moon. In Medieval England it was known as the Chaste Moon.
I’ve long been quite entranced with the full moon names and their variations. Of course, they reflect both the need to mark passing time and the way that time was experienced by people who were living close to the land. Lunar time-keeping pre-dated our modern calendars (and some calendars, like the Jewish and Chinese calendars, are still lunar-based.) The Farmer’s Almanac has a good list of Native American full moon names and how each came to be.
Lots of people garden using the phases of the moon. The good news is that there isn’t one best time to plant — Each aspect of planting has an associated moon phase, based on how much moisture is pulled up through the soil by the monthly pull of the moon (much the way the moon influences the tides.)
The time just after the full moon is an especially good time for planting root crops, as the gravitational pull is high (adding more moisture to the soil) and the moonlight is decreasing, contributing energy to the roots. For this reason, the waning moon is also a good time to plant bulbs and transplants.
Enjoy the new season and the supermoon!
