The time, it is a-changing. Daylight Saving Time is back, meaning that you should, prior to going to sleep tonight, move your clocks ahead by an hour. And while you're at it, check the batteries in your smoke alarms.
For sticklers, the official time to set clocks forward by an hour is 2 a.m. Sunday morning. As with all things in life, there are exceptions. Not all U.S. states pay attention to the time change. All of Hawaii and most of Arizona ignore it. The Navajo Indian Reservation in Arizona does recognize the time change. Indiana used to be split on the idea, but state legislation in 2006 now has all Hoosiers on board with the change. After all, why should a confusing time-changing rule be simple?
Daylight Saving Time was first officially implemented during WWI, as a way to save energy. These days, the value of DST is regularly debated.
The next clock adjustment, moving clocks back for an hour, will happen in November. That is the month to look forward to — or to fall back on, depending on how you feel about the whole thing.
