>Months always have 30 or 31 days in them >False. February. Duh. This one in particular rubbed me the wrong way. But if it were rewritten as something like "Don't forget about February, which is normally 28 days, unless it is a leap year in which it case it is 29 days long. But did you know that if the year is divisible by 100, we skip the leap day? Unless the year is also divisible by 400, in which case, we DO include the leap day. So even the exception has exceptions." Or something like that. Adds a little more detail on top of what is fairly obvious.
