Remember, Remember, the Date of the Month

I'm sort of hurrying this post along. I remembered a thought that I had before, and realized that, since I have a blog, I should probably put it up while it's still on the day.
I'd just like to point out that the remembering scheme for Guy Fawkes Day is a bit odd. For those who don't know, it goes:
"Remember, remember, the fifth of November."
The problem with this is that the last part - which is what this is used to recall anyway - could be any of several dates in September, November, or December. The "fifth" is not even required to rhyme with anything, so any monosyllabic ordinal will do.
