Don't know if this project i still active - there seem to be no changes in a long time... but anyways I installed that plugin yesterday and did some improvements for German support i want to share.

Translation

I did the complete translation for the plugin. Except for the term "Field define progress value for ticket." since i didn't know in which context it is used.

-> see attached ganttcalendar.po (locale/de/LC_MESSAGES/) and compiled ganttcalendar.mo

Layout

I did some layout improvements to gantt.html to fit the needs here in germany better ;)

• changed date notation from YYYY/MM/DD to DD.MM.YYYY
• improved the weekday representation at some zoom-levels
• changed the notation of weeks to week-numbers (but attention there are different numbering systems out there. the one i used is valid for germany and probably some other regions)

So maybe you'd like to include these things :)
