Instead of using 2 simpledate format, you can parse them on same date format after parsing, you get 2 dates. You can find the miliseconds difference with :

`

long differenceAsMs = higherDate.getTime() - lowerDate.getTime();
int differenceAsDay = differenceAsMs / (1000 * 60 * 60 * 24);

` Hope this helps.

You can try this function:

public String getDateDiffString(Date dateOne, Date dateTwo)
{
    long timeOne = dateOne.getTime();
    long timeTwo = dateTwo.getTime();
    long oneDay = 1000 * 60 * 60 * 24;
    long delta = (timeTwo - timeOne) / oneDay;

    if (delta > 0) {
        return "dateTwo is " + delta + " days after dateOne";
    }
    else {
        delta *= -1;
        return "dateTwo is " + delta + " days before dateOne";
    }
}

Use joda time library: JodaOrg/joda-time · GitHub

LocalDate date1 = new LocalDate(2014, 5, 25);
LocalDate date2 = new LocalDate(2014, 6, 15);

Period period = new Period(date1, date2, PeriodType.yearMonthDay());

int daysBetween = period.getDays();
int monthsBetween = period.getMonths();
int yearsBetween = period.getYears();

Note that period will return negative numbers if date2's date is before date1's date, it'll return positive numbers otherwise.
