When using the schedule on an android phone with RTL layout enabled(Phone language is Hebrew) and attempting to move to a certain date an exception is thrown.

The situation DOES NOT occur when the phone layout is LTR(Phone language is EN(us)).

Exception Log:

[0:] System.DivideByZeroException: Attempted to divide by zero.

I have a SfCalendar above the SfSchedule(both are inside a scroll view which is inside a stacklayout), was trying to move the Schedule date when a date is selected in the calendar. SfSchedule is set to DAY VIEW.

Code Sample:

Schedule.MoveToDate =  Calendar.SelectedDate.Value;
