About Daylight Savings Time

Mar 9, 2020 | South Pasadena

Each year in South Pasadena and many other parts of the world, in the wee hours of a Sunday morning in March, 60 minutes vanish from the clock and the time reappears each year in November! No, it's not a magic trick — it's Daylight Saving Time!  

Daylight Saving Time (DST) was created to make better use of the long sunlight hours of the summer. By “springing" clocks forward an hour in March, we move an hour of daylight from the morning to the evening. On the first Sunday in November, we “fall back" and rewind our clocks to return to Standard Time.

But, who thought of this crazy idea? And how is it useful? Well, the idea was first suggested in an essay by Benjamin Franklin in 1784, and later proposed to British Parliament by Englishman William Willett 1907. However, it did not become a standard practice in the United States until 1966. Daylight Saving Time was originally instituted in the United States during World War I and World War II in order to take advantage of longer daylight hours and save energy for the war production. In the years after World War II, individual states and communities decided whether they wanted to continue observing Daylight Saving Time and when to do so. This meant some cities were an hour behind others even though they were only separated by a few miles on a map. In order to minimize the confusion, Congress passed the Uniform Time Act in 1966, which standardized the length of Daylight Saving Time for the country.

In the United States, there are only a few places that do not observe Daylight Saving Time, including parts of Arizona, Hawaii, Puerto Rico, the U.S. Virgin Islands and American Samoa. There are currently about 70 countries that participate in Daylight Saving Time, though not necessarily on the same schedule as the United States. Determining who recognizes Daylight Saving Time and when can sound like a very complicated math word problem.  Let's just say that it gets complicated.

Advocates in support of Daylight Saving Time suggest that in addition to reducing crime and automobile accidents, extended daylight hours also improve energy conservation by allowing people to use less energy to light their businesses and homes. Opposing studies argue the energy saved during Daylight Saving Time is offset by greater energy use during the darker autumn and winter months.
