 Intent myIntent = new Intent(Main.this, MyAlarmService.class);
 pendingIntent = PendingIntent.getService(Main.this, 0, myIntent, 0);

    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

    Calendar cal = Calendar.getInstance();

    cal.setTimeInMillis(System.currentTimeMillis());
    cal.clear();
    cal.set(2012,5,20,18,40);

    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

Use setRepeating Method of Alarm Manager and

add exact one year in date which you have fetched from db

Calendar today_plus_year = Calendar.getInstance();  
today_plus_year.add( Calendar.YEAR, 1 );

After that convert it into milliseconds and pass into alarm manager setRepeat method

alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

     if (cDate.equals(dbDate)) {
    Log.i("TODAY", "Dates Matched");
    Log.i("TIME MATCHED", "Currently in AM");
    cal.set(Calendar.HOUR_OF_DAY, hour);
    cal.set(Calendar.MINUTE, minutes);
    cal.set(Calendar.SECOND, 0);
    Intent intent = new Intent(this, AlarmReciever.class);
    PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0,intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
    // am.setRepeating(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),
        AlarmManager.INTERVAL_FIFTEEN_MINUTES, operation);

    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pi);
    } 
   else {

   }
}

and also this code is even not calling the broad cast service — Vishal Sharma, Feb 07 '13 at 05:11
