Perhaps, but I&#x27;m not so sure that was the reason for the definition.<p>For example, I know the dates of the solstices and equinoxes, and I&#x27;m (at best) a casual gardener.    The fact those dates don&#x27;t align with what I think of as the start of the seasons doesn&#x27;t prevent me from remembering them.<p>In the location I do most of my growing, I&#x27;m actually more interested in tracking first and last frost - these are the primary constraints on many crops.  These certainly don&#x27;t align with equinoxes or solstices, let alone 1sts of months.<p>Farmers, presumably, are even more intimately aware of the usual dates (and variances) for these events in their region.   That&#x27;s why I don&#x27;t think it was the reason for labelling the solstice &#x2F; equinox as the start of each season.
