Before you go to bed on Saturday, make sure you turn your clock forward. With that simple act, you'll get an extra hour of daylight, an extra hour of outside playtime and a sure sign that spring and summer are here for good. All of that is fun, but is that really why we "spring forward?"
The idea of daylight saving time started with Benjamin Franklin, who also helped set up the postal system and write the Declaration of Independence. (Man, that guy was smart!) In an essay published in 1784, he wrote about how the sun rises well before most people wake up, and sets well before most people go to sleep, especially during spring, summer and fall.
He went on to explain how a lot of the money spent on candles used for light (this was before there was electricity) could be saved if everyone woke up earlier and went to bed earlier. That way, there would be less time between sunset and bedtime, so fewer candles would be needed during the evening.
Even though Franklin's idea made sense, most people didn't want to get up earlier than they had to.
