        int month = 8;    // Replace with the desired month
        
        YearMonth yearMonth = YearMonth.of(year, month);
        
        LocalDate firstDayOfMonth = yearMonth.atDay(1);
        LocalDate lastDayOfMonth = yearMonth.atEndOfMonth();
        
        System.out.println("First day of " + yearMonth + ": " + firstDayOfMonth);
        System.out.println("Last day of " + yearMonth + ": " + lastDayOfMonth);
    }

Last day of 2023-08: 2023-08-31
