For those of you in the US, don't forget to set your clocks ahead one hour! Unless you live in Arizona, Hawaii, or half of Indiana. And since I was a little curious this morning, I thought you might appreciate a little history regarding this strange phenomenon (especially in Indiana. How does half a state change it's time like that? Weird).

Every spring we move our clocks one hour ahead and "lose" an hour during the night and each fall we move our clocks back one hour and "gain" an extra hour. But Daylight Saving Time (and not Daylight Savings Time with an "s") wasn't just created to confuse our schedules.
The phrase "Spring forward, fall back" helps people remember how Daylight Saving time affects their clocks. At 2 a.m. on the first Sunday in April, we set our clocks forward one hour ahead of standard time ("spring forward"). We "fall back" at 2 a.m. on the last Sunday in October by setting our clock back one hour and thus returning to standard time. The change to Daylight Saving Time allows us to use less energy in lighting our homes by taking advantage of the longer and later daylight hours.

During the six-and-a-half-month period of Daylight Saving Time, the names of time in each of the time zones in the U.S. changes as well. Eastern Standard Time (EST) becomes Eastern Daylight Time, Central Standard Time (CST) becomes Central Daylight Time (CDT), Mountain Standard Time (MST) becomes Mountain Daylight Tome (MDT), Pacific Standard Time becomes Pacific Daylight Time (PDT), and so forth.
Daylight Saving Time was instituted in the United States during World War I in order to save energy for war production by taking advantage of the later hours of daylight between April and October. During World War II the federal government again required the states to observe the time change. Between the wars and after World War II, states and communities chose whether or not to observe Daylight Saving Time. In 1966, Congress passed the Uniform Time Act which standardized the length of Daylight Saving Time. Arizona, Hawaii, parts of Indiana, Puerto Rico, the U.S. Virgin Islands, and American Samoa have chosen not to observe Daylight Saving Time.
Other parts of the world observe Daylight Saving Time as well. While European nations have been taking advantage of the time change for decades, in 1996 the European Union (EU) standardized a EU-wide "summertime period." The EU version of Daylight Saving Time runs from the last Sunday in March through the last Sunday in October. During the summer, Russia's clocks are two hours ahead of standard time. During the winter, all 11 of the Russian time zones are an hour ahead of standard time. During the summer months, Russian clocks are advanced another hour ahead. With their high latitude, the two hours of Daylight Saving Time really helps to save daylight. In the southern hemisphere where summer comes in December, Daylight Saving Time is observed from October to March. Equatorial and tropical countries (lower latitudes) don't observe Daylight Saving Time since the daylight hours are similar during every season, so there's no advantage to moving clocks forward during the summer.
The next time you're changing your clocks for Daylight Saving Time, remember that it's not just trying to mess up your schedule but its purpose is to save energy.
