String getAgeInOther(int year, int month, int day) {
    Calendar today = Calendar.getInstance();
    Calendar birth = Calendar.getInstance();
    birth.set(year, month, day);
    Calendar temp = Calendar.getInstance();
    temp.set(year, month, day);
    int totalDays = 0;

    int intMonth=0,intDays=0;

    for (int iYear = birth.get(Calendar.YEAR); iYear <= today.get(Calendar.YEAR); iYear++) {
        if (iYear == today.get(Calendar.YEAR) && iYear == birth.get(Calendar.YEAR)) {

            for (int iMonth = birth.get(Calendar.MONTH); iMonth <= today.get(Calendar.MONTH); iMonth++) {
                temp.set(iYear, iMonth, 1);
                if ((iMonth == today.get(Calendar.MONTH)) && (iMonth == birth.get(Calendar.MONTH))) {

                    totalDays += today.get(Calendar.DAY_OF_MONTH) - birth.get(Calendar.DAY_OF_MONTH);

                } else if ((iMonth != today.get(Calendar.MONTH)) && (iMonth != birth.get(Calendar.MONTH))) {

                    totalDays += temp.getActualMaximum(Calendar.DAY_OF_MONTH);
                    intMonth++;

                }else  if ((iMonth == birth.get(Calendar.MONTH))) {

                    totalDays +=( birth.getActualMaximum(Calendar.DAY_OF_MONTH)- birth.get(Calendar.DAY_OF_MONTH));

                } else  if ((iMonth == today.get(Calendar.MONTH))){

                    totalDays += today.get(Calendar.DAY_OF_MONTH);



                    if (birth.get(Calendar.DAY_OF_MONTH)
