Explaining the PowerPivot Calendar Chart, Plus an Updated XLSX Download

Well the CalChart post was a hit - the second most popular post of this year in fact. (Second only to Dan Battagin's spreadsheet formatting post, and that one had the benefit of being directly linked to from the official Excel blog - Dan is a big cheater).

I particularly enjoy how many Excel Pros are arriving at this blog for the first time as a result of the CalChart - you know who you are! You're helpless against the luxuriant charms of the CalChart!

And you have to have PowerPivot for it to work, muhaha. Resistance is futile. Go download it from Microsoft now. It's free.
