midwinter as said before is a cultural event..it is the midpoint
between light and dark at the winter solstice, and was a traditional celebration which
had its roots in when winter started around this point,livestock
that were not expected to survive the winter would be culled
with the glut of extra food they used to have the celebration of rebirth
not really connected to the actual seasons as we see them now
if 21st of dec is mid winter...when did winter start...maybe after 21st of
june when the nights start to draw in, doesnt make much sense as thats
the start of summer.
like you said it depends where you live....and as we live in the uk
winter starts officially on the 21st of december
