Why is 11am + 1 hour == 12:00pm?

I can never remember if noon is 12pm or 12am. I’ve always ascribed this to having grown up in Finland, where we use 24-hour clock. But it’s actually not that unreasonable to be confused, as this brilliant StackExchange answer explains.

I came across this while re-reading Zach Holman’s UTC is enough for everyone, right?.
