    Default Re: calculating number of days between 2 dates chosen in jdateChooser

    You can extract the long values that represent the values of those dates. This give you date information in milliseconds. Subtract the first date with the second will give you the different in milliseconds. To get the values in days you need to divide the milliseconds value with (24 * 60 * 60 * 1000).

    Another way is to use the Joda Time, and it will be much simpler, the snippet look like this.

    Java Code:
    import org.joda.time.DateMidnight;
    import org.joda.time.Days;
    DateMidnight start = new DateMidnight("2010-02-01");
    DateMidnight end = new DateMidnight("2012-02-07");
    int days = Days.daysBetween(start, end).getDays();
