> My high school, for example, ended at 2:18pm (I can still picture the clock), but I think this was a consequence of starting at 7:30am. That's interesting. If your classes are 45 mins or an hour long and you get 5, 10 or 15 minutes to get to your next class, how do you end up with 2:18pm? Also, even if it was 2:18pm, I'd imagine most schools would just round that up to 2:20pm or let you leave a few minutes earlier at 2:15pm. I don't ever recall any of my classes ending in a none-round number ( time that didn't end with a 0 or a 5 ). I don't recall any school letting me out at a none-round number. As a matter of fact, I don't recall any stores, government offices or tv shows that didn't open or start at a "round number". And every meeting I've had ( even multiple meetings in a day ) always was at a "round number". I can't imagine saying lets start the meeting at 2:17pm. Most of the time we'd bump it to 2:30pm. And if we were constrained for time to 2:20pm.
