calendar calendar = calendar.getinstance();  calendar.add(calendar.date, -2); 

you can use simpledateformat parse string date based on pattern of choice - in case yyyymmdd.

then can perform operations on date want re-format string based on pattern.

simpledateformat sdf = new simpledateformat("yyyymmdd"); //set simpledateformat per pattern     string datestr = "20140310"; // date string     calendar cal = calendar.getinstance();     cal.settime(sdf.parse(datestr)); // set date calendar instance     cal.add(calendar.date, -2); // perform operation      system.out.println(sdf.format(cal.gettime())); //20140308
