I wish they would. It plays havoc with my body clock. My alarm is set for 7 am. Of course all this week I have been clicking awake at 6 am, and so has my daughter (guess I know who’s body clock she inherited). Pick a time frame and stick with it!
In two weeks I will be going from the east coast to the west and gain three hours. Then 11 days later I will reverse it. Just get used to it!
Now the reason is that parents don’t want their kids going to school in darkness. Why don’t they just skip the whole thing. Studies have shown that, contrary to belief, DST saves no energy. Yes, those long pleasant summer evenings are nice but I can live without them. And most people are huddled in their air-conditioned dens watching TV anyway, the real reason (the AC, not the TV) that DST doesn’t save energy. I would be on my porch but for the skeeters.
It has only changed once since we adopted a national standard in 1966. In 2007, we moved the switch back one week, from the last Sunday in October to the first Sunday in November. (the start of DST was moved back twice, first in 1986 and again in 2007).
We tried this in 1974, during the OPEC oil embargo. It was almost universally despised, and a government study found no benefit in terms of either energy savings or reduced traffic fatalities.
In 2010, Daylight Saving started on March 14 and ends on November 7. That means that we were on Standard Time approximately 127 days out of 365 or 34.8% of the time. So Standard Time is the standard only 1/3 of the year.
There’s still one reason to stay with DST. Around here, in the summer, the sun would come up at about 4:30 a.m. and set about 7:30 p.m. With DST that turns into 5:30-8:30. In the winter, daylight hours are about 6:30 a.m. - 5:00 p.m. If DST were year round, it would be 7:30-6:00.
Of course I live in the middle of the time zone, in the middle of the latitudes. I understand YMMV.
I wouldn’t have minded yearlong DST when I lived in the higher latitudes; having it be darkest night at 430pm makes me require medication; it was the one thing I could never get used to - not the cold or the snow, not the slick sidewalks, it was the early darkness that killed me. Then again I can understand that conversely not having the sun rise until 9 am could have a similar effect on many others.
Hmm… I wonder if at least for a big chunk of the population, this could be dealt with by modifying the actual time zone borders…
I agree with you that one time system for the year would be great. But it makes the most sense to have a 12-hour clock that at least corresponds with something natural as the day. Timing it to be roughly zenith and the middle of the night is both traditional and sound.
(If you imagine that this would rob you of precious evening light in summer, ask why almost everyone decides to get up an hour earlier but pretend it’s later during Daylight Savings.)
For those of you who think year 'round DST is good, I presume you live on the eastern side of your time zone. With year 'round DST, here’s a sample of some sunrise times on January 1st:
[li]Indianapolis: 9:06am[/li][li]Salt Lake: 8:52am[/li][li]Boise: 9:18am[/li][li]Bismark: 9:26am[/li][/ul]
Here in Boston, sunrise wouldn’t be until 8:12 am, and I find that unacceptable.
