The calendar pop will show a different starting day or the week dpendiong how where it is called. For exmple the issue navigator popup is correct but the work log one is wrong.

We have 2 ways to invoke the datepicker

macros.vm for Velocity files and datepicker2.jsp. The first one is correct

    Calendar.setup({
        firstDay    : ($currentCalendar.firstDayOfWeek) -1,              // first day of the week

and the second one (datepicker2) is wrong

        Calendar.setup({
            firstDay     : <%= Calendar.getInstance(locale).getFirstDayOfWeek()%>,              // first day of the week

The reason the -1 is needed is that the Calendar js uses 0 as Sunday, and 1 as Monday while Java uses 1 as Sunday and 2 as Monday

We need to fix this. Its a very easy fix.

As a work around customers need to change

template/standard/datepicker.jsp and template/single/datepicker.jsp

you should change line 69 to be

        Calendar.setup({
            firstDay     : <%= Calendar.getInstance(locale).getFirstDayOfWeek() -1 %>,              // first day of the week
