12 Month Calendar with Summary Tab

[flyonthewall]

It's budgeting season for me (YAY!) and I'm looking to create a 12 month calendar, 1 month per tab, with a summary page that comes first with a listing of all events that are scheduled in each month. As we add events/deadlines into a particular day, the summary tab would add it to the list. It doesn't need any other information other than the event. Few questions:

1. Anyone know of an existing template that already does this?
2. Should I even bother doing this in excel? I suppose I could create an outlook calendar?
3. TIA for any advice.
