Mabon blessings from the Southern Hemisphere.
This is the second thing that I have seen saying it is the first day of spring. In the USA, does the equinox traditionally mark the transition from winter to spring (or summer to autumn)? If so, is that a formal or informal thing?
The reason I ask is, in Australia we formally define the seasons according to the calendar months - our (official) shift from summer to autumn occurred on March 1, and autumn will last for the months of March, April and May. Arbitrary nonsense of course, but I was under the impression that delineating the seasons formally in this way was pretty standard for England and its one-time colonies.
If the equinox marks the shift from winter to spring over there (and presumably, summer to autumn), what dates mark the shift from spring to summer, and autumn to winter?
