Difference in Days between two Java dates?

Question

I want to get the difference between two Java Date objects. I've used Joda-Time library. But the problem is that I'm getting the Days greater difference than that of actual day difference.

Here's my code snippet:

DateFormat formatter = new SimpleDateFormat("mm/dd/yyyy");

Date someDate=new Date();
Date today = Calendar.getInstance().getTime();

try     {
    someDate = formatter.parse("06/22/2010");
}
catch(ParseException pe)    {
    System.out.println("Parser Exception");
}

int days = Days.daysBetween(new DateTime(someDate), new DateTime(today)).getDays();

System.out.println(" Days Between " + someDate + " : " + today + " - " + days);

Here's my output:

 Days Between Fri Jan 22 00:06:00 IST 2010 : Sun Jul 25 19:27:01 IST 2010 - 184

Here, Why does it takes "06/22/2010" as Jan 22? Does anyone face similar problem?

Help me friends.. Thanx in advance..

It seems like mm refers to minutes, not months, which is MM. Please check here to see the list of appropriate lettering :)
