Answer 1

Or I'll just post them here to save the trouble...
    Calendar xmas = new GregorianCalendar(1998, Calendar.DECEMBER, 25);
    Calendar newyears = new GregorianCalendar(1999, Calendar.JANUARY, 1);
    // Determine which is earlier
    boolean b = xmas.after(newyears);            // false
    b = xmas.before(newyears);                   // true
    // Get difference in milliseconds
    long diffMillis = newyears.getTimeInMillis()-xmas.getTimeInMillis();
    // Get difference in seconds
    long diffSecs = diffMillis/(1000);           // 604800
    // Get difference in minutes
    long diffMins = diffMillis/(60*1000);        // 10080
    // Get difference in hours
    long diffHours = diffMillis/(60*60*1000);    // 168
    // Get difference in days
    long diffDays = diffMillis/(24*60*60*1000);  // 7
