NSDateComponents - day method returning wrong day

I can't seem to figure out why the day doesn't change when I get to the 6th of November, 2011. All I'm doing is iterating through the days. Any help would be appreciated. Here is my code:

NSCalendar* calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents* comp = [[NSDateComponents alloc] init];

[comp setDay:2];
[comp setMonth:11];
[comp setYear:2011];

NSDate* date = [calendar dateFromComponents:comp];

for (int i = 0; i < 7; i++) {
    NSDate* d = [date dateByAddingTimeInterval:((3600 * 24) * i)];
    NSDateComponents* dComponents = [calendar components:(NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit) fromDate:d];

    int day = [dComponents day];
    NSLog(@"\nDate: %@\nDay: %i", [d description], day);
}

This is my output:

Date: 2011-11-02 06:00:00 +0000
Day: 2

Date: 2011-11-03 06:00:00 +0000
Day: 3

Date: 2011-11-04 06:00:00 +0000
Day: 4

Date: 2011-11-05 06:00:00 +0000
Day: 5

Date: 2011-11-06 06:00:00 +0000
Day: 6

Date: 2011-11-07 06:00:00 +0000
Day: 6

Date: 2011-11-08 06:00:00 +0000
Day: 7

Thanks!
