Daylight Saving Time

Have you ever wondered why you have to change the clocks one hour ahead in the spring and one hour back in the fall? Daylight Saving Time is a popular practice in many countries. Each spring, we begin Daylight Saving Time by moving the clocks ahead one hour. In the fall, we move the clock back one hour to return to Standard Time. Many countries practice Daylight Saving Time as a way to conserve energy. Because the length of the day is longer, less electricity is used.

Here are some fun facts about Daylight Saving Time:

  • More than 70 countries use Daylight Saving Time in at least part of their country.
  • Beginning in 2007, Daylight Saving Time was extended. It starts each year in March and ends in November.
  • In the U.S., Hawaii and some parts of Arizona do not use Daylight Saving Time.
  • Daylight Saving Time was first used in the U.S. in 1918. It was used in parts of Canada beginning in 1908.
  • A popular expression to remember how to move your clock is “Spring forward, fall back.”
