NSDateComponents *components2 = [calendar2 components:units2 fromDate:date2];
int startWeekDay = [components2 weekday];
[date2 release];
[calendar2 release];

Edit for Mac:

The format of the string has to be —YYYY-MM-DD HH:MM:SS ±HHMM according to the docs, all fields mandatory

Old answer (for iPhone and tested on simulator):

There is no (public) -initWithString: method in NSDate, and what you get returned is not what you expect.

Use a properly configured (you need to give the input format) NSDateFormatter and -dateFromString:.
