This weekend marks the end of Daylight Saving Time. The return to standard time comes at 2 a.m. Sunday November 1st. Like the saying goes, “spring forward in spring “fall back” in the fall. That calls for setting clocks back one hour. That is if the clock doesn’t do so automatically. Most choose to set their clock back when you go to bed Saturday, then your clocks will be right on time when you get up Sunday morning. Though the concept of time change has been around since the 1700’s Daylight Saving Time did not become law in the U.S. until 1966, when President Lyndon Johnson signed the Uniform Time Act. Not without its critics- Arizona and Hawaii for example don’t even HAVE Daylight Saving Time- the time change supporters say it saves on energy costs. Again, Daylight Saving Time ends this Sunday at 2 a.m. Clocks that do not automatically reset for the time change will need to be manually set back one hour. Experts also say the time switch is a good way to remember to change smoke alarm batteries.
