[affablelochan]

How can i change the label for work week. Currently it is displayed as #. I would like to rename into something.

Generally if i want to make changes to the qcalender where should i refer. Is there a manual page or something? My only source of information is the example code at this point. I take the code and make changes according to my need. Example i wanted to change # --> work week. I have no clue as to where or how to make this change.
