Working with dates


I have some problems with showing dates in Scheduler.

In the day-view header (tab), there are no problems, as it show as of the Danish way (par ex : 31 okt 2011 (maybe a missing 31. okt 2011), but not important in this matter.

In the week-view header (tab), there are no problems as it shows the Danish way (par ex : 31 okt 2011, but each day in the week, shows the english way of date format (okt 31) and not the Danish way (31 okt).

Where do I change this, or can you direct me to more info ?.
