Hello, precisceness!
That's on my first page of notes in one of my classes (Real-time systems). He told us to memorize it for the exam, as a joke, and somebody in my class really did memorize it, also as a joke. *shrug*
In that same class, my prof was telling us that DST was invented to help stores make more money. Since people don't like shopping in the dark, they extended days by an hour to give stores an hour more business in the summer, which is also the reason they're extending it. In December, people will shop anyway. And in January/February, nobody shops anyway.
He didn't cite his source on this information, but I wouldn't be at all surprised if that's the actual reason.
That's what I've heard too.
Also, there are a bunch of counties around the country (USA, FYI) that don't do DST. It's annoying, because you'll be in some town, drive five minutes, and have to change your clock. Also, there are some weird places that only do 30 minutes of DST...
