What Are The Odds?

What are the odds of being able to get your adsense payment on the same date as a past month with a similar calendar?

Let me explain.

October 2007 has the same calendar day layout as January 2007. In January 2007 I got my adsense payment on the 23rd - so I was kind of hoping that the same thing would occur this month since the 2 months are exactly similar.

Well its October 24th and still no sign of that "payment in progress" line on my adsense account.

It just goes to show you that adsense's payment schedule has no rhyme or reason.
