Spring equinox is March 20


March means clocks, the spring equinox and (the following month) a full moon named for phlox.

Daylight saving time returned March 14 (it’s now MDT instead of MST) and the 2021 spring equinox will take place at 3:37 a.m. Saturday, March 20. The March full moon, the Full Worm Moon, follows at 12:50 p.m. Sunday, March 28, according to almanac.com.

Because it is the first full moon after the spring equinox, March’s full moon is the Paschal Full Moon, the website said. That means its date determines the 2021 date of Easter (April 4). Paschal comes from Pascha, the Greek and Latin word for Passover.

Easter is always held on a Sunday between March 22 and April 25. Because the Christian Church follows a calendar created in 325 A.D., ecclesiastical dates for the full moon and spring equinox may differ from astrological dates.

Full moon names used by The Old Farmer’s Almanac come from Native American, Colonial American and European sources, the website said.

The March Worm Moon may refer to the earthworms that appear as the soil warms in spring. Or, according to alamanac.com, it could be because Capt. Jonathan Carver, an 18th-century explorer, wrote that this moon name refers to beetle larvae beginning to emerge from the thawing bark of trees and other winter hideouts.

April’s Full Pink Moon (named for creeping or moss phlox, also known as moss pink, an early springtime wildflower native to eastern North America) occurs at 9:33 p.m. Monday, April 26. May’s Full Flower Moon (named for all the emerging blooms) is at 5:14 a.m. Wednesday, May 26. June’s Full Strawberry Moon (Algonquin tribes knew it as a signal to harvest strawberries) is at 12:40 p.m. Thursday, June 24.
