- Benjamin Franklin first suggested adjusting clocks a couple times a year as a way to better sync shop schedules with the seasons, thus saving on lighting costs ("Daylight Saving Time," 2008).
- Though many countries have had some form of Daylight Saving Time since World War I, it only became widespread in the US with a federal regulation passed in 1966 ("Daylight Saving Time," 2005).
- US states can decide whether or not to participate in DST; Arizona and Hawaii are currently the only two states that do not ("Daylight Saving Time," 2008).
- In 2007, the US shifted the spring and fall dates for Daylight Saving Time in order to save energy. As a result, "the measure reduced U.S. energy consumption by 17 trillion Btu, enough to power 175,000 households for a year" (Hutchinson, 2009).
