ELI: Why do we need daylight saving time?

I understand it changes the time to adjust between the seasons, but why?

Easy: We don't.

DST is a man-made idea to change the feel of the day. We work and play when the sun's up and sleep when it's dark, right? Think of this - You need to get up every day at 7AM to get ready for work or school. In the spring, daylight starts at 6:30 and goes until as late as 8PM in the summer. But when winter comes, days get shorter, and daylight starts at 6:00. Well without DST, you would "waste" daylight because at 6:00 when the sun comes up you'd still be sleeping until the alarm goes off at 7:00. Therefore, the government decided that we should set our clocks back so that we wake up when the sun comes up, "resetting time" so that sunrise is our new 7AM.
