I know, 2011 has already started a few weeks ago. However, I still owe you the DIY Planner calendar. Of course, the calendar differs from Ygor’s template in having week numbers on all templates. This year, I translated it to German as well, so you can have the German or the English version for download.
Unfortunately, I haven’t been able yet to create a Windows executable that runs without any additional library. So you have to build the version from your own scratch. The source code is available at my Subversion repository.
