-(NSString*) getWeekOfMonth {
  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
 [dateFormatter setDateStyle:NSDateFormatterMediumStyle];
 [dateFormatter setTimeStyle:NSDateFormatterShortStyle];
 [dateFormatter setDateFormat:@"W"];

 NSString *weekNumber = [dateFormatter stringFromDate:[NSDate date]];    
 [dateFormatter release];    
 return weekNumber;
}

NSInteger weekInt = [weekNumber integerValue];
