So I been working on this program and I have gotten some dates to work out fine but when I input the month of February with a future year it shows that its invalid when it shouldn't be. For the sake of this program days in February are just 1-28. Can anyone help me catch my mistake?

  import java.util.Scanner;
    public class FutureDate {
     public static void main (String args[]){

  int inputMonth;
  int inputDate;
  int inputYear;
  final int currentMonth = 10;
  final int currentDate = 24;
  final int currentYear = 2013;
  final int numberOfDays = 31; 

  Scanner keyboard = new Scanner(System.in);

  System.out.println("Enter a month in format - mm: ");
  inputMonth = keyboard.nextInt();

  System.out.println("Enter a day in format - dd: ");
  inputDate= keyboard.nextInt();

  System.out.println("Enter a year in format - yyyy: ");
  inputYear = keyboard.nextInt();


  if (inputYear < currentYear)
  System.out.println("Invalid Date");

  else if (inputYear >= currentYear)


  {

     if (inputMonth >= 1 && inputMonth <=12){        

        if ((inputMonth == 4 || inputMonth == 6 || inputMonth == 9 || inputMonth == 11) && (inputDate >= 1 && inputDate <= 30))
        System.out.println("Valid Date");

        else if (inputMonth > currentMonth && inputDate >= 1 && inputDate <=30)
        System.out.println("Valid Date");

        else if (inputMonth == currentMonth && inputDate > currentDate && inputDate <=30)
        System.out.println("Valid Date");

        else

        System.out.println("Invalid Date");
        }

     else if (inputMonth == 2 && inputDate >= 1 && inputDate <= 28){
        System.out.println("Valid Date");

        if (inputMonth > currentMonth && inputDate >= 1 && inputDate <=28)
        System.out.println("Valid Date");

        else if (inputMonth == currentMonth && inputDate > currentDate && inputDate<=28)
        System.out.println("Valid Date");

        else
        System.out.println("Invalid Date");
        } 

      else if (inputMonth == 1 || inputMonth == 3 || inputMonth == 5 || inputMonth == 7 || inputMonth ==10 || inputMonth == 12 && inputDate >= 1 && inputDate <= 31){

        if (inputMonth > currentMonth && inputDate >= 1 && inputDate <=31)
        System.out.println("Valid Date");

        else if (inputMonth == currentMonth && inputDate > currentDate && inputDate <=31)
        System.out.println("Valid Date");

        else
        System.out.println("Invalid Date");

     }

      else           
      System.out.println ("Invalid Date");

        }

  }

  }
