Auto-Populating Excel Calendar

I am looking for an excel calendar that will auto-populate content into it based on a spreadsheet that I fill in.

Maybe I would just need the formula that would be inserted into each calendar day? I'm not sure how you would set this up, but I'm open to suggestions!

I have attached the .xls file for your reference.

For example: The comment "Client 1 - KOM" would populate in a blank calendar in excel on the date 3/23/2009.

Thanks in advance,

Vince
