If you live in the parts of the U.S. and Canada that observe Daylight Saving Time, don't forget to move your clocks back an hour tonight. It couldn't come soon enough, though this is the soonest it can come under the 2007 changes to DST observance.
This morning's 7:22 sunrise in Chicago is the latest we'll have to endure until next November 1st, but tonight's 5:47 sunset is the latest we'll get to have until March 6th. Tomorrow the sun rises at 6:23 and sets at 4:45, as our available daylight shrinks from 10 hours, 24 minutes today down to 9 hours, 7 minutes on December 21st.
I'm not a fan of the 2007 changes. I like switching to DST in the spring and switching back in the fall, but I also believe that mid-October (or even the end of September as they do in Europe) makes a lot more sense. At least mornings aren't so gloomy in the fall. (Not a lot we can do about the post-7am sunrises from December 2nd through February 5th, but we expect those two months to be gloomy.)
Of course, I'm not in Chicago at the moment, and it's plenty sunny here...
