date - Java Calendar Object subtracts a month

I'm trying to fill a calendar object by doing this:

Date now = new Date(System.currentTimeMillis());
Calendar cal = Calendar.getInstance();
    cal.setTime(now);

It is now 2013-11-26 but when I print out

cal.get(Calendar.MONTH)

it will return 10.

How can I fix this?

You need not to fix it. It's Calendar behavior.

cal.get(Calendar.MONTH)

you are using System.currentTimeMillis() that is the current month.

Return 10 because the months starts from 0. So 10 is the 11th month. I.e Nov

0-Jan
1-Feb
