No worries. I'll test it on a Linux server.
The way your code parses the dates, however, is something to consider in the future. At the moment, the names of the weekdays appear fine on the top row of the monthly calendar view. However, when I switch to 'weekly view' they turn into question marks. Obviously, you code pulls the information about the weekdays differently, in the two different cases.
Thanks for the promt reply. This is a great extension, and I'm looking forward to its stable release.
