Spring Ahead 2011!

[Methanolic]

Do it today!!


I always pay close attention to this one. Later this afternoon I will set all the clocks ahead in my house. It feels horrible to wait til Sunday to change them and have the day lose that hour.


Sunday, March 13, 2011 at 2:00:00 AM clocks are turned forward 1 hour

Am I dreaming in thinking this was always done on the 21st in the past?

Yes, you're thinking of the solstice. The clock change was never on a specific 'date'.

Though it has been moved up a number of weeks in recent years.

Worst weekend of the year.

Good idea to turn them ahead this afternoon. Nothing sucks more than waking up on Sunday realizing it's actually an hour later than what you though it was.

[sergei_makarov]

Losing that hour of rest really screws with me for a good while.

[Cecil Terwilliger]

I'm already sleep deprived from waking up so damn early every day. This is definitely not going to help.

[stampsx2]

Go to bed when you're not tired.
Wake up when you should still be sleeping
and lose an hour of sleep on top of it.


One hour ahead sucks.

[scotty2hotty]

Agreed that losing an hour of sleep sucks.

Still being light outside at 7pm tomorrow is pretty sweet though.

[TylerSVT]

I like the later days... hate the dark mornings again though.

A long time ago, it used to be the last Sunday of April. Then, sometime during the Reagan administration, it was changed to the first Sunday of April. Then, a couple of years ago, it was moved to the second Sunday of March (and the end of DST was moved back a week from the last Sunday of October to the first Sunday of November).

It used to be pretty much six months of DST and six months of standard time. Now, it's barely 4 months of standard time.

Thankfully, with all this extra daylight, it should help the weather warm up nicely.

Also be extra careful driving to work on Monday morning. Worst non-weather related commute of the year with everyone more tired than normal.

I don't mean to be too skeptical but is there statistical proof to this or is it just an old wives tale?

I could see it being true and I think I've heard that before but never backed up with any actual source that shows that even with ideal conditions accidents are still at a statistical higher occurance.

If it means we're closer to summer, I'm ok with losing an hour. Not sure about you guys, but I'm finding -15 and colder is getting old.

We used data from a tabulation of all traffic accidents in Canada as they were reported to the Canadian Ministry of Transport for the years 1991 and 1992 by all 10 provinces. A total of 1,398,784 accidents were coded according to the date of occurrence. Data for analysis were restricted to the Monday preceding the week of the change due to daylight savings time, the Monday immediately after, and the Monday one week after the change, for both spring and fall time shifts.



The loss of one hour's sleep associated with the spring shift to daylight savings time increased the risk of accidents. The Monday immediately after the shift showed a relative risk of 1.086 (95 percent confidence interval, 1.029 to 1.145; ξ2 = 9.01, 1 df; P<0.01). As compared with the accident rate a week later, the relative risk for the Monday immediately after the shift was 1.070 (95 percent confidence interval, 1.015 to 1.129; ξ2 = 6.19, 1 df; P<0.05).

Thus, the spring shift to daylight savings time, and the concomitant loss of one hour of sleep, resulted in an average increase in traffic accidents of approximately 8 percent, whereas the fall shift resulted in a decrease in accidents of approximately the same magnitude immediately after the time shift.

Taken together then, these data are consistent with the hypothesis that as a society were are sufficiently chronically sleep deprived so that a small decrease in sleep duration, such as that which occurs with the spring shift to DST, can significantly increase accident susceptibility.

According to a McMaster University study called “Sleep Deficit, Fatal Accidents and the Spring Shift to Daylight Savings Time,” traffic crashes during the Monday following the weekend of turning the clock ahead one hour increased by a significant 17 per cent compared to the average Monday.

No way you did all that in 8 minutes. You must have had that post all ready to go and then just copied and pasted.

Very impressive either way and thank you for the insanely quick response (even if it wasn't you I was doubting.)

Are we allowed to change the clocks before we go to bed? I thought we weren't supposed to change them until 2am? That's what I've always been doing.

Waking up at 2am just to change my clocks always pissed me off.

You're allowed to do whatever you please in your own home!

Woosh.

[Maritime Q-Scout]

Be extra careful if you're driving tonight, you don't want to have the police turn on their lights and siren at 1:59am and stop you at 3:01am then charge you for an hour long chase
