Daylight Saving Time is this Sunday, which means clocks will “fall back” an hour. The clocks roll back one hour at 2 a.m. on Sunday, Nov. 3. The official time in the U.S. will be 1 a.m. This means that most of us will get an extra hour of sleep but darkness will come an hour early as well. This week, A B Pest Control & Insulation thought it would be fun to share some facts and history about Daylight Saving Time.
Here are some facts about the twice-yearly time change:
- Sunday, March 10, 2019 – Daylight Saving Time began at 2 a.m. this year
- It is “Daylight Saving Time” (singular), not “Daylight Savings Time” (plural). We are “saving daylight” for the end of the day.
- Since 2007, Daylight Saving Time starts in the United States on the second Sunday in March, and ends on the first Sunday in November.
The timeline of how Daylight Saving Time (DST) came to be:
- 1784 – The idea of daylight saving is first conceived by Benjamin Franklin.
- 1914-1918 – Britain goes on DST during World War I.
- March 19, 1918 – The Standard Time Act establishes time zones and daylight saving. DST is repealed in 1919, but continues to be recognized in certain areas of the United States.
- 1945-1966 – There is no federal law regarding DST.
- 1966 – The Uniform Time Act of 1966 establishes the system of uniform DST throughout the United States. The dates are the last Sunday in April to the last Sunday in October. States can exempt themselves from participation.
- 1974-1975 – Congress extends DST in order to save energy during the energy crisis.
- 1986-2006 – DST begins on the first Sunday in April and ends on the last Sunday in October.
- August 8, 2005 – President George W. Bush signs the Energy Policy Act of 2005 into law. Part of the act extends DST starting in 2007, from the second Sunday in March to the first Sunday in November.
- 2007 – Under the new laws, all of Indiana now observes DST, where only certain areas of the state did before.
- Exceptions in the United States: Hawaii and most of Arizona
- The US territories of Guam, Puerto Rico, Virgin Islands and American Samoa also do not observe DST.
- About 70 countries around the world observe DST. Japan and China do not.
- Many countries near the equator do not adjust their clocks for DST.
