In this post I have attached a simple calendar template that will allow you to generate a new calendar by just changing the month name or year.

You can enter in dates and cash flows in the data tab and they will populate on the calendar for those days. Of course the formulas can be overridden to put other data in the calendar.
Below is what the template looks like with some sample cash flow numbers filled in
