It’s that time of year again- the time where we “fall back” one hour from Daylight Savings Time to Standard Time. Many of us like this weekend because we get a badly-needed extra hour of sleep.
The “official” time to turn back the clocks is 2:00 A.M. on Sunday, November 6th. If you’re like most people, you’ll just turn all of your clocks back right before you go to bed on Saturday night. Of course the days will be getting shorter and the nights will be getting longer until we reach the winter solstice, which occurs for us this year at 12:30 A.M. on December 22, 2011. That will be the day in the year with the least hours of sunlight (the day when the sun reaches its southernmost point in the sky at noon local time). After that the days start getting longer again.
Although we complain about having to get up in the dark and come home in the dark, remember it could be worse. The farther north you go in the northern hemisphere, the shorter the hours of daylight. People who live north of the Arctic Circle towards the North Pole won’t have any daylight at all!
Here’s a bit of trivia for you: did you know that the 4 seasons aren’t of equal length? The earth moves around the sun not in a circular orbit but in an elliptical orbit, so it travels at different speeds. In the northern hemisphere, spring is 92.8 days long, summer is 93.6 days long, autumn 89.8 days and winter 89.0 days. So spring and summer are longer than fall or winter.
Enjoy your weekend!
