You need to account for leap-years:
Code:
    else if(imonth == 2) {
      if (iyear % 4) {
        iday = 28;
      }
       else {
        iday = 29;
      }
    }

Please keep in mind that this will only work properly if your dates occurs between the years 1901 and 2099. A more accurate implemention would be:
Code:
     else if(imonth == 2) {
      if (iyear % 400) {
        if (iyear % 100) {
          if (iyear % 4) {
            iday= 28;
          }
          else {
            iday = 29;
          }
        }
        else {
          iday= 28;
        }
      }
       else {
        iday = 29;
      }
    }
