Last months dates go to 32. Looking at your screenshots it didn't do it at one point but does it now. Know of a fix? I don't mind fixing for you but since it seems to be rather recent maybe it's something you could just roll back.

how to show previous month and previous year of month as usual now show in your project current month and next month also next year of month...please help me

Thank @kenumir so much for this best Calendar library.

I custom your calendar and show correctly from Monday to Sunday with respective day.

Now I want show from Sunday to Monday.

• I'm able to show the Title from Sunday to Monday.
• But the Day not show respectively with.

I try to set locale or setFirstDayOfWeek but looks not work as I thought.

in CalendarCard.java

 private void updateCells(boolean isRefresh, ArrayList<CardGridItem> o) {
               Calendar cal;
               Integer counter = 0;

        if (mCalendarDateDisplay != null)	cal = (Calendar) mCalendarDateDisplay.clone();
        else	cal = Calendar.getInstance();

        /*
         * Set specified specifiedMonth to refresh if have
         */
        if (isRefresh)  cal.set(Calendar.MONTH, getSpecifiedMonth());
        cal.set(Calendar.DAY_OF_MONTH, 1);

        int daySpacing = getDaySpacing(cal.get(Calendar.DAY_OF_WEEK));

        /*
         DAY IN PREVIOUS MONTH
          */
        if (daySpacing > 0) {
            Calendar mCalPrevMonth = (Calendar)cal.clone();

            mCalPrevMonth.add(Calendar.MONTH, -1);
            mCalPrevMonth.set(Calendar.DAY_OF_MONTH, mCalPrevMonth.getActualMaximum(Calendar.DAY_OF_MONTH) - daySpacing + 1);

            for(int i=0; i<daySpacing; i++) {
                CheckableLayout cell = cells.get(counter);
                cell.setTag(

                cells.get(i).setVisibility(View.GONE);
            }
        }
    }`

Therefore I post this enhancement,
Please help me detail how to do this?

Thank you,

On load the cells are rectangle in the first two pages, go to page 3 and they are square, go back to page 1 and the these cells are now square, is there a way of keeping the cells square at all times
