From javadocs:

set

public final void set(int year,
                  int month,
                  int date)

Sets the values for the calendar fields YEAR, MONTH, and DAY_OF_MONTH. Previous values of other calendar fields are retained. If this is not desired, call clear() first. Parameters: year - the value used to set the YEAR calendar field. month - the value used to set the MONTH calendar field. Month value is 0-based. e.g., 0 for January. date - the value used to set the DAY_OF_MONTH calendar field.

months is zero index based. You need to have 10 instead of 11.

Alternatively instread of using integers directly, you can write meaningfully.

 c.set(1991,Calendar.NOVEMBER, 12);

Where Calendar.NOVEMBER is a static int field which represents NOVEMBER.

Month value is 0-based. e.g., 0 for January.

You have to change 

c.set(1991, 11, 12);

To

c.set(1991, 10, 12);

January is Month 0, so when you set 11 that is December Check java.util.Date docs
