Summer starts officially... tomorrow!

I know, I know! You are probably saying that Summer Solstice (for those in the Southern Hemisphere), or more generally, December Solstice, is today at 23:38 UTC (11:38pm).

However, if you live where I live, South Africa (or further east), Summer Solstice, which marks the official start of summer in the Southern Hemisphere, only starts tomorrow. In South Africa, Summer Solstice is at 01:38 (1:38am) tomorrow morning, Wednesday, 22 December 2010! New Zealand’s Summer Solstice is at 12:38 (pm), Wednesday, 22 December 2010.

In short, summer will officially start without me knowing about it or experiencing it. I will be sleeping! Well, at 01:38, most sane people are usually asleep. And, hopefully, I am sane!
