Is this a better way of remembering the number of days in a month?

You are probably familiar with the rhyme that begins Thirty days has September. How about this instead: Before August, odd numbered months have an odd number of days.

There is even a story that goes with this. It has no factual basis, but it fits in nicely with the calendar. According to the story, the Romans, logical thinkers that they were, set up the calendar so that all odd numbered months had 31 (an odd number) days and all even numbered months had 30 days, except for February, which only had 30 days in leap years and 29 days otherwise. The problem started when August was named for Augustus Caesar. He felt resentful that Julius Caesar’s month, July, had 31 days but his month only had 30. He ordered that a day be moved from February to August and all the months after August be rearranged so they would still alternate months with 30 and 31 days.

I was reminded of this by xkcd’s comic for today The character would find it easier to just have to think that since October comes after August, the month’s even numbered parity of 10 is the opposite of its odd numbered day parity of 31.
