    Default GregorianCalendar - How to figure out how many days in all weeks of March, 2013?

    HI,
    I could calculate the number of weeks in any month and year using following method.

    public void calWeeksAndDays(int month, in year)
    {
    GregorianCalendar cal = new GregorianCalendar(year, month, 1);

    int weeks = cal.getActualMaximum(WEEK_OF_MONTH);

    }

    This works as expected, but now how do I figure out how many days are in each of the weeks that I got from above?

    Aren't there 7 days in each week?

    Not necessarily. For example: March 2013 has actually 4 full weeks and two partial ones. The first week of March has only 2 days, i.e. Thursday March 1 and Friday March 2. While the last week of March has only 1 day, that is Sunday Mar 31.

    So that's what I want to figure out.

    Ohhhh.

    So isn't the number of days in the partial week = number of days in the month less the number of full weeks * 7?

    Hello.
    Check the name of the first day of the month. Based on that you will know whether its a partial week or full week. If its partial week you will know how many days. If its full then its 7 days. You will also know how many maximum days are there in that month.
    After finishing with first week start increments of seven until you cross the maximum days. If you have crossed the maximum days then decrement by 7 and count the remaining days. Those will be the number of days for the last week.
