Duplicating spreadsheet across a year

[pepsi]

Hello,

I've created a spreadsheet for some project I'm doing. I want to duplicate the first page across 12months (on different spreadsheets)

I want to keep all formatting/formulas and all dates, but I have date formats such as 1-jan-2012 - 31-jan-2012 (on the new spreadsheet I want that to change to Feb etc)

I have uploaded the spreadsheet for your reference
