Fetch All Upcoming Friends of Facebook Friends Days, Not Just for Current Year

I am writing a Facebook Android application in which I am trying to get a list of all upcoming facebook friends' birthdays, and I can get it.

But I ran into a problem, I only collect a list of friends until the end of December for this year, not all coming , like today, March 15, so I want to get a list of facebook friends who are born today, until March 14, but I get today until 31 December.

See the code below and help me solve this little problem:

    Calendar cal = Calendar.getInstance();
    Date today = cal.getTime();
    SimpleDateFormat formatter = new SimpleDateFormat("MM/dd");
    String today_formatted = formatter.format(today);
    String query = "select name, birthday, uid, pic_square FROM user " +
    "WHERE uid in (SELECT uid2 FROM friend WHERE uid1 = me()) AND birthday_date != 'null' " +
    "AND birthday_date >= '" + today_formatted + "'ORDER BY birthday_date ASC";
