I've modified the calendar code from...
http://support.microsoft.com/kb/213795
"...How to Create a Monthly Calendar"
and put it in a .xls workbook with two sheets: "2 Month Calendar" & "1 Month Calendar".
Click the button on the appropriate sheet to generate the calendar.
The workbook code module is unlocked so the modified code is viewable.
If anyone would like a (free) copy, email and ask for "Multi Month Calendar".
I request that you use your real name and provide your geographic location.
