I believe it's much simpler that that.
every month is 4 weeks, except the last of any quarter (March, June, Sep, Dec). As well as that, every once in a while there's an extra 5 week month (which happened this year, hence January)
At least, I'm pretty sure that's how NPD does it. Anyone have any objections?
Help! I'm stuck in a forum signature!
