David Seah over at http://davidseah.com has published a great compact printable calendar for the last few years. They are great for project planning, especially when it comes time to figure out Releases or to help figure out that a deliverable 8 weeks from now lands on a critical resources vacation time.
I usually carry one around in my notebook and mark it up until it’s time to print out a new one. Very handy.
He also has several other useful tools worth checking out that I’ve used in the past, all part of his Printable CEO series. Specifically, I’ve used the Emergent Task Timer and Emergent Task Planner. Check them out here.
Here is the link to the calendar. Note, it does require a spreadsheet program like Excel, but it works as well in free options like OpenOffice.
