Daylight-saving time was started during World War I to save oil and other energy resources needed for the war. It was used again in WWII, then became a law in 1966. Only a few states and regions don't follow it. We start Daylight Saving Time at 2 a.m., the first Sunday in April, and go back to Standard Time on the last Sunday in October. With an extra hour of daylight after dinner in the summer, people don't need to use their lights as long, so they waste less electricity and that saves energy. In 2005 Bush passed his so called Energy act by extending Daylight saving Time. There is considerable doubt that any energy is actually saved due to the already short days in fall and spring and the long days in summer aren't actually effected by shifting time.

The dates we switch will probably change again

New York is in the Eastern Time Zone. Next comes Central Time, then Mountain, then Pacific. Each one is one hour earlier than the one before.
Arizona is one of the few U.S. states or regions (along with Hawaii, eastern Indiana, Puerto Rico, U.S. Virgin Islands, and American Samoa) that do not follow Daylight Saving Time. This messes me up because my daughter lives in Arizona and my brother lives in California, so for part of the year their time is the same.

In April, we "spring ahead" and lose an hour while we sleep. The hour between 2 a.m. and 3 a.m. doesn't exist that night! We can nap on Sunday usually, especially if we missed Church :-).  The next day though is a school/work day and has one of highest accident rates of the year

The Babylonians were the ones to divide up the hour by 60. They used the base-60 system (called sexagesimal) for their astronomy. Since 60 can be divided by 2, 3, 4, 5, 6, and 10, it simplifies large calculations. That made it a reasonable choice to divide up the parts of the hour as well.
