How to subtract two calendar objects in Android

Let's say for example I have two calendar objects with the format "MM / dd / yyyy". How do I subtract them and return the number of days? For example, "9/7/2014" is "9/1/2014" and returns 7.

Calendar calendar = Calendar.getInstance();
Calendar today = Calendar.getInstance();
+3

You can try this:



Calendar calendar = Calendar.getInstance();
  calendar.set(Calendar.DAY_OF_MONTH,7);
  calendar.set(Calendar.MONTH,8); 
  calendar.set(Calendar.YEAR, 2014);

  Calendar today = Calendar.getInstance();

  long difference = today.getTimeInMillis() - calendar.getTimeInMillis();
  int days = (int) (difference/ (1000*60*60*24));
+8
