There is a growing movement to call the vernal (spring) equinox the March Equinox or Northward Equinox to avoid “Northern Hemisphere bias.”
While the spring equinox typically occurs on March 20 or 21, meteorological spring begins on March 1, a month when average temperatures increase by 10 degrees over the month.
At Chichen Itza, Mexico, the Mayan celebrate the first day of spring with “The Return of the Sun Serpent.” On the evening on the spring equinox, the setting sun creates a triangular shadow on the El Castillo pyramid that looks like a descending snake, or the feather serpent god Kukulkan.
The myth that it is possible to balance an egg on its end on the spring equinox is just that: a myth. Trying to balance an oval-shaped object on its end is no easier on the spring equinox than on any other day.
While some people prefer not to feed birds in spring and summer, during the spring migration, a feeder might be a useful source of food for traveling birds.
