Answer 1

Convert both dates into calender and make time 0(

today.set(Calendar.HOUR_OF_DAY, 0);
    today.set(Calendar.MINUTE, 0);
    today.set(Calendar.SECOND, 0);

).
Then use this fun :

public final static long SECOND_MILLIS = 1000;
public final static long MINUTE_MILLIS = SECOND_MILLIS*60;
public final static long HOUR_MILLIS = MINUTE_MILLIS*60;
public final static long DAY_MILLIS = HOUR_MILLIS*24;

 public static int daysDiff( Date earlierDate, Date laterDate )
    {
        if( earlierDate == null || laterDate == null ) return 0;
        return (int)((laterDate.getTime()/DAY_MILLIS) - (earlierDate.getTime()/DAY_MILLIS));
    }
