Calendar returns wrong month

I want to retrieve the date and time for my application, for which I wrote the following code

Calendar c = Calendar.getInstance();
System.err.println("Date is: " + c.get(Calendar.DATE));
System.err.println("Month is: " + c.get(Calendar.MONTH));
System.err.println("Year is: " + c.get(Calendar.YEAR));
System.err.println("Hour is: " + c.get(Calendar.HOUR_OF_DAY));

However the preceding code snippet is providing incorrect result.

SEVERE: Date is: 31
SEVERE: Month is: 11
SEVERE: Year is: 2012
SEVERE: Hour is: 17 

NOTE: The time on my machine is perfect, no problem there

Answer 1

You are expecting 12 instead of 11 for the month.

c.get(Calendar.MONTH) returns 0 based index.

From the javadoc :

public static final int MONTH

Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.
