Fall back
Remember that Daylight Saving Time ends (in most of the US, anyway) tonight. On the plus side, yay for an extra hour of sleep! On the minus side, alas for the time of sunset (already too early for my tastes) suddenly getting an hour earlier.
I had been under the impression that DST was ending later than usual this year, but turns out I was wrong; it still ends on the last Sunday in October through next year. Starting in 2007, though, DST will start three weeks earlier and end a week later.
