I understand exactly what you're saying, and no I'm not stupid. Thumbs have knuckles, and there is a dip between the index and thumb. You can't just discount those because you want to.

Guess I just don't agree on how to count fingers, since you absolutely DO have a webbing of skin that counts as a dip after your index finger. The only case that could be made for no dip would be for the months of September and October. You are creating random definitions of dips and knuckles to make your way work, therefore it doesn't actually make sense.

So now you are arbitrarily deciding which dips count and which don't? That makes literally no sense, and that way of counting is absurd. You can't say it's a pattern, then go and interrupt the pattern 4 repetitions in just to make your little "memory charm" make sense.

... but that doesn't work?? July and August are in a row and both contain 31 days.
