Daylight Saving Time
BEGINS
this weekend...
Here is a look at some other interesting facts about daylight saving time:
1. The idea of daylight saving was first proposed in 1895 by English-born New Zealander George Vernon Hudson, but it was first implemented by Germany and Austria-Hungary in April 1916.
2. Many countries have daylight saving time at various times since 1916, but most countries consistently use it since the energy crises of the 1970s.
3. As mentioned above, not all places in the United States spring forward the clocks. Hawaii and most of Arizona do not observe daylight saving time. Nor does Puerto Rico.
4. Adding daylight to evenings benefits retailing, sports, and other activities that exploit sunlight after working hours,but can cause problems for evening entertainment and other occupations tied to the sun (such as farming) or to darkness (such as firework shows).
5. Clock shifts are usually scheduled near a weekend midnight to lessen disruption to weekday schedules.
6. A 2009 U.S. study found that on Mondays after the switch to daylight saving time, workers sleep an average of 40 minutes less, and are injured at work more often and more severely.
7. Studies on daylight saving time have mixed results when it comes to effects on health.
8. Not all countries begin and end daylight saving time on the same day. For instance, France, Spain, and the United Kingdom won’t spring forward until March 30. Since 1996 European Summer Time has been observed from the last Sunday in March to the last Sunday in October.
9. Daylight saving time is generally not observed near the equator, where sunrise times do not vary enough to justify it.
10. Only a minority of the world’s population uses daylight saving time because Asia and Africa generally do not observe it.
