00:00We're jumping into November and you know what that first weekend brings? The dreaded clock change.
00:05But this one hits a little different because we fall back 2 a.m. Sunday morning.
00:10For most it comes down to an extra hour of sleep as we turn a 48-hour weekend into 49 hours.
00:15But why do we do it? Believe it or not, people have been doing it for centuries, at least in some capacity.
00:21In ancient times before clocks, the sunlight was used to track the days, so a shift in time for higher latitudes came naturally.
00:28But as society became less driven by agriculture, it became harder to just go by the sun.
00:33Let's face it, we like when the school bus comes at the same time each day and when we can go to work at the same time.
00:39In the U.S., standard time and time zones had become well established with the development of the railroad by 1883.
00:45But it wasn't until Standard Time Act of 1918 that daylight saving and time zones were officially established.
00:53Daylight saving time was repealed just one year later, but locally many places still did it.
00:57It was then that it was reestablished a few months after the U.S. entered World War II and remained in use through the war.
01:05After that, it dropped away in some locations and the Uniform Time Act came in 1966, the standardized daylight saving time.
01:14But the dates still shifted around a little bit.
01:17And we've actually entered daylight saving time anywhere from early January to the end of February and even the last week of April.
01:23And while there are still benefits to aligning society's day with the sun, some spots in the U.S. don't partake in the fun.
01:30Most U.S. territories, as well as Hawaii and most of Arizona, do not do daylight saving time.
01:36For the rest of us, though, don't forget to set those clocks back this weekend an hour earlier as we catch that extra hour this coming weekend.
01:46And of course, too, if you're looking forward to the next clock change, it's coming right around the corner, 128 days away.
