The Winter Solstice - 21/12/2010 23:38 UTC

So Winter Solstice is upon us again and the usual argument is brewing. Begining, middle or end of winter? As a kid, I was taught that the winter months were November, December and January. As an astronomy buff that makes sense to me. The sun reaches its lowest annual noontime point in the sky, sometime around December 21st, before begining its climb back up again towards the summer solstice. This year's exact solstice will be on December 21, at 23:38 UTC. The noticeable effect of this is that the days begin to gradually get longer again, although this isn't obvious immediately afterwards. Traditionally, December 21st was described as midwinter, June 21st being midsummer.

Some good info here:

.....and as it happens, on this auspicious occasion, I turn 36.
