/*
  Java difference between dates example shows how to
  calculate difference between two dates using Java 
  Calendar object.

import java.util.Calendar;
 
public class DateDifferenceExample{
 
        public static void main(String[] args){
        
        //get instance of Calendar objects
        Calendar cal1 = Calendar.getInstance();
        Calendar cal2 = Calendar.getInstance();
        
        //set two dates we want to know difference of
        cal1.set(2006, 12, 30);
        cal2.set(2007, 5, 3);
        
        long milis1 = cal1.getTimeInMillis();   
        long milis2 = cal2.getTimeInMillis();
        
        //difference in milliseconds
        long diff = milis2 - milis1;
        
        //difference in seconds
        long diffSeconds = diff / 1000;
        
        //difference in minutes
        long diffMinutes = diff / (60 * 1000);
        
        //difference in hours
        long diffHours = diff / (60 * 60 * 1000);
        
        //difference in days
        long diffDays = diff / (24 * 60 * 60 * 1000);
        
        System.out.println("Date difference in milliseconds: " + diff + " milliseconds.");      
        System.out.println("Date difference in seconds: " + diffSeconds + " seconds."); 
        System.out.println("Date difference in minutes: " + diffMinutes + " minutes."); 
        System.out.println("Date difference in hours: " + diffHours + " hours.");       
        System.out.println("Date difference in days: " + diffDays + " days.");
        
        }
}
 
/*
Output of above date difference program would be
Date difference in milliseconds: 10713600000 milliseconds.
Date difference in seconds: 10713600 seconds.
Date difference in minutes: 178560 minutes.
Date difference in hours: 2976 hours.
Date difference in days: 124 days.
