When we change our clocks

When we change our clocks

Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time.

In the European Union, Summer Time begins and ends at 1:00 a.m. Universal Time (Greenwich Mean Time). It begins the last Sunday in March and ends the last Sunday in October. In the EU, all time zones change at the same moment.




Spring forward, Fall back

During DST, clocks are turned forward an hour, effectively moving an hour of daylight from the morning to the evening.







Spelling and grammar

The official spelling is Daylight Saving Time, not Daylight SavingS Time.

Saving is used here as a verbal adjective (a participle). It modifies time and tells us more about its nature; namely, that it is characterized by the activity of saving daylight. It is a saving daylight kind of time. Because of this, it would be more accurate to refer to DST as daylight-saving time. Similar examples would be a mind-expanding book or a man-eating tiger. Saving is used in the same way as saving a ball game, rather than as a savings account.

Nevertheless, many people feel the word savings (with an 's') flows more mellifluously off the tongue. Daylight Savings Time is also in common usage, and can be found in dictionaries.

Adding to the confusion is that the phrase Daylight Saving Time is inaccurate, since no daylight is actually saved. Daylight Shifting Time would be better, and Daylight Time Shifting more accurate, but neither is politically desirable.


When in the morning?

In the U.S., clocks change at 2:00 a.m. local time. In spring, clocks spring forward from 1:59 a.m. to 3:00 a.m.; in fall, clocks fall back from 1:59 a.m. to 1:00 a.m. In the EU, clocks change at 1:00 a.m. Universal Time. In spring, clocks spring forward from 12:59 a.m. to 2:00 a.m.; in fall, clocks fall back from 1:59 a.m. to 1:00 a.m.

In the United States, Daylight Saving Time commences at 2:00 a.m. to minimize disruption. However, many states restrict bars from serving alcohol between 2:00 a.m. and 6:00 a.m. At 2:00 a.m. in the fall, however, the time switches back one hour. So, can bars serve alcohol for that additional hour? Some states claim that bars actually stop serving liquor at 1:59 a.m., so they have already stopped serving when the time reverts to Standard Time. Other states get solve the problem by saying that liquor can be served until "two hours after midnight." In practice, however, many establishments stay open an extra hour in the fall.

In the U.S., 2:00 a.m. was originally chosen as the changeover time because it was practical and minimized disruption. Most people were at home and this was the time when the fewest trains were running. It is late enough to minimally affect bars and restaurants, and it prevents the day from switching to yesterday, which would be confusing. It is early enough that the entire continental U.S. switches by daybreak, and the changeover occurs before most early shift workers and early churchgoers are affected.


Some U.S. areas

For the U.S. and its territories, Daylight Saving Time is NOT observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, the Commonwealth of Northern Mariana Islands, and Arizona. The Navajo Nation participates in the Daylight Saving Time policy, even in Arizona, due to its large size and location in three states.


A safety reminder

Many fire departments encourage people to change the batteries in their smoke detectors when they change their clocks because Daylight Saving Time provides a convenient reminder. "A working smoke detector more than doubles a person's chances of surviving a home fire," says William McNabb of the Troy Fire Department in Michigan. More than 90 percent of homes in the United States have smoke detectors, but one-third are estimated to have dead or missing batteries.

With the time change we get an extra hours sleep. Plus the bar stays open an extra hour if it closes at 2:00 am. Both sounds good to me, lol

I just wated to add this as I have a newer home and thought they were hard wired which they are, but they also have a battery back up..

Newer homes are equipped with interconnected hardwired devices, many of which have a battery back up...time to change those batteries as well.

If your device is more than 10 years old, get a new alarm...change 1, change em all. 10 year lithium battery models are now available. Look for photo electric with the hush feature.

Remember that 50% of Canadian homes do not have a working smoke alarm...don't be an idiot...smoke alarms don't need files to run...they need power.

Public service announcement for the day.

Happy testing.

You got some good points, Rob. Thx for the post.

When Clocks Change, Body May Need Time to Adjust




That extra hour of sleep you'll get in most parts of the country on Sunday might be restful, but the end of Daylight Saving Time could spell trouble for your body clock, a sleep expert says.


Dr. Atul Malhotra, medical director of the sleep disorders research program in the division of sleep medicine at Brigham and Women's Hospital in Boston, explained in a hospital news release that there are ways to prevent the time change from disrupting your sleep habits.


For most people, the time shift in the spring is more problematic because an hour is "lost" rather than "gained," but for those who are disrupted by any change in schedule, Malhotra offered these coping tips:

Stay away from caffeine and other stimulants, especially during the days before and after the time shift, and avoid napping for a few days because it can disrupt your sleeping at night.
Sleep through that extra hour if you can instead of trying to get things done.
Don't drive if you feel sleepy because of the time shift. Consider taking public transportation for a few days to give your body time to adjust.
Relax, avoid stress and remember to take your regular medications over the weekend of the time change.

For those who have trouble sleeping overall, Malhotra suggested the following:

Go to bed and wake up at the same times, even on weekends. No sleeping in.
Avoid food and drinks with caffeine after lunch, including coffee, tea, soda and chocolate.
Take 15 to 30 minutes to wind down before heading off to bed.
Keep your room dark, quiet and cool; ear plugs and eye masks can help.
Keep in mind that time in front of screens -- the computer or television varieties -- before bedtime can disrupt sleep.
Don't work or study right before bedtime, in order to allow yourself to relax.
Don't exercise strenuously right before bedtime.
