This seems to crop up every year. British meteorologists and
climatologists take winter as the months of December, January and
February and spring as March, April and May. That seems eminently
sensible to me. Using complete months makes calculating averages for
each season simpler, and also on average the first three weeks of March
are warmer than the first three weeks of December. There's no good
reason why spring should be considered to begin at the Vernal Equinox,
at least as far as weather and climate are concerned.

I would have thought February 5th would have been the ideal date. It is half
way between the solstice and equinox, so using that as a base line,
mid-summers day, 21st June or the summer solstice, would then be literally
mid-summer.

It brings Mr Spock to mind. Nothing humans do is ever logical.
