Syntax
Numeric getActualMinuteMaximum()
        Usage
This method
                considers the given time value and the current values of the
                    
        getFirstDayOfWeek(),
                    getMinimalDaysInFirstWeek(), and setTimeZone()
                methods. For example, if the date of this instance is February 1, 2004, the actual
                maximum value of the Day of Month field is 29 because 2004 is a
                leap year, and if the date of this instance is February 1, 2005, it's 28. Note: This
                    method calculates the maximum value of the field Week of Year based on the Year
                    value, not the 
Week of Year. Call
                        getWeeksInWeekYear() to get the maximum value of
                        Week of Year in the week year of this calendar.
