Why Do We Change our Clocks Twice a Year?

This weekend we "Spring" forward an hour, but why?

As much as I am looking forward to the extra hour of daylight at the end of the day, I'm dreading losing an hour of sleep this weekend haha!  It got me wondering, why do we change our clocks twice a year?

Well to figure it out we first have to learn about Daylight Saving Time.  Daylight Saving time is when we "spring" forward an hour, and according to Wonderopolis.org “Daylight Saving Time was originally instituted in the United States during World War I and World War II in order to take advantage of longer daylight hours and save energy for the war production”

And as Webexhibits.org explains Daylight saving as “The main purpose of Daylight Saving Time is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening”

So why don't we just stay on Daylight Savings Time?  Why do we have to turn it back?

Well I literally cannot find anything online that says why we turn them back... so the only thing I can think of is so we can move that hour of daylight back to the morning?  Which I guess kind of makes sense, but I'm not a fan of it getting dark early in the evening.   What do you think?  Should we continue to change the clocks, or just leave them alone??
