Incorrect date obtained after processing

Question

I run the following code and obtain incorrect date (instead of 1/2/2015 6:00:00 AM it prints 12/28/2015 6:00:00 AM):

    SimpleDateFormat _sdf = new SimpleDateFormat("M/d/YYYY  H:mm:ss a");
    _time = "02/01/2015  6:00:00 AM";
    Date date;
    try {
        date = _sdf.parse(_time);
        Calendar calendar = GregorianCalendar.getInstance();
        calendar.setTime(date);
        _time = _sdf.format(calendar.getTime());
        System.out.println(_time);  // 12/28/2015  6:00:00 AM   !!!
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Are you sure you actually get all the way to `_sdf.format()`? I think `setTime()` does not swallow anything but an instance of `Date`. — , Mar 23 '16 at 14:08

Try to use this:

SimpleDateFormat _sdf = new SimpleDateFormat("M/d/yyyy  H:mm:ss a");

i.e, you need to use yyyy instead if YYYY.

Check the Oracle Docs

y   Year    Year    1996; 96
Y   Week year   Year    2009; 09
