Daylight Saving Time

Daylight Savings Time (DST), also known as Summer Time or Spring Forward/Fall Back, changes the clocks forward 1 hour in the summer months to give an extra hour of daylight in the evenings, then changes the clocks back 1 hour after the summer is over. Times vary by country and year and some countries may change the date for various reasons. less then half of the countries in the world use Daylight Saving Time and the ones who do may not use it in all regions. 

In the United States, Hawaii and Arizona do not observe DST, while the rest of the country does. 

Daylight Saving Time History

The concept of Daylight Saving has a long history dating back to ancient civilizations who were flexible in their daylight timekeeping. In more modern times, DST was implemented during the wartime in the early 1900's to save on energy. It was abandoned by some countries after the war but then re-adopted at varying times. 

Future of Daylight Savings Time

Today, there are many who think we should stay on DST permanently. Some countries have while others continue to Spring Forward and Fall back every year.
