The week number either in the calendar grid of the Work & Vacation view or in the Gantt view is off by one. It shows one less than the week number in KDE's calendar on the system tray. Today (2013-06-17), it shows week number 24, and KDE's calendar shows 25. I tried to debug it but couldn't find the area of code where this is being calculated. Reproducible: Always
I found it's a problem in KCalendarSystem const KCalendarSystem * calendar = KGlobal::locale()->calendar(); const int weekNumber = calendar->week( pCellDate ); Example: 2013-06-16 should return 25, but it returns 24. Locale is set to start week on Sundays
But did you also set the "Week number system:" in locale settings? Because by default it is on "ISO Week", for which it is expressly stated that weeks start on Monday for the purpose of numbering them. Two other options, "Full First Week" and "Partial First Week", claim to take into account the set starting day of the week.
It returns the correct week number on Mondays, so the problem is on the calculation of the first day of the week, not the starting week. I forgot to add Monday in my previous example. Example: 2013-06-16 should return 25, but it returns 24. 2013-06-17 returns 25 (OK)
But what about the "Week number system:" setting, in System Settings "Region and Language" module? As I explained above, if it is set to default value of "ISO Week", then Monday is taken as first weekday in week numbering, regardless of the actual setting of week start day.
That's the issue then. Calligra Plan and Korganizer are only taking the "First day of week" setting, not realizing that ISO Week numbering system can modify the first day of week too. Thanks for the clarification. I'll move this back to Calligra, because it has to be fixed there.
