displayedMonth

The Bikram Sambat month the grid is showing.

While displayedCalendarSystem is CalendarSystem.GREGORIAN the grid pages over Gregorian months, and this reports the Bikram Sambat month holding the first day of the visible one. Assigning still works in either calendar: the grid moves to whichever of its own months contains the first day of the month you assign. Use displayedMonthCalendar when you want the month exactly as displayed.
