if condition always returns true (Java)

I am trying to implement a date system that inevitably displays tomorrows day, month and year.

The problem I am having is that the one of the if statements always returns true, and the ones after this one always return false.

Here is part of my code:

public class dateVerification {

    int tomorrowDay = 0;
    int tomorrowMonth = 0;
    int tomorrowYear = 0;
    int day = 0;
    int month = 0;
    int year = 0;

    public void date() {

        Scanner myScanner = new Scanner(System.in);
        System.out.println("Enter the day");
        day = myScanner.nextInt();
        System.out.println("Enter the month");
        month = myScanner.nextInt();
        System.out.println("Enter the year");
        year = myScanner.nextInt();

        switch (month) {
            case 1:
                if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10) {
                    if (day < 31) {
                        tomorrowDay = day + 1;
                    } else {
                        tomorrowDay = 1;
                        tomorrowMonth = month + 1;
                    }
                }
                break;

The line that is returning true is:

 if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10)

And everything else is returning false, i.e. my case 2 statement

if (month == 4 || month == 6 || month == 9 || month == 11)

Can anybody shed some light on this?
