Production Calendar in Excel Format
This is very similar in style to the one PSMKay first posted:
Sample production calendar in word format.
But is in Excel format, which I prefer. It also has formulas in it to make it easier to begin a calendar on any particular day (simply delete the numbers prior to First ACTUAL date of the month and that day will become "1")
There are three tabs to the file.
The first ("Monthly") is the template calendar (12 times so you can do a whole year at once).
The second ("Mini Months") is a sheet with all possible starting days to a month. These are mini calendars which can be inserted into one of the blocks of the larger calendar so you can quickly glance at the next/previous month.
The third (HELMET July 2007) is my sample calendar for the show I'm starting preproduction work on so you might see how it all comes together.
I did a lot of work on making a full template so that I don't have to waste time messing around with creating a calendar in the future.
