How do you calculate the day of the year for a specific date in Objective C

I am looking for a way to find the day number which has past in current year. For example if today was 2013-03-22 , then the number should be 81, because 81 day has past in 2013 year. It doesn't matter if it is a leap year or not.

So if anybody has some links or even a way how to do it, please share it with me. Thanks in advance!

you can try using the unix timestamp as it is universal ... u can then manipulate any date using that — madLokesh, Jan 21 '13 at 08:16

Try this:

NSCalendar *currentCalendar = [NSCalendar currentCalendar];
NSDate *today = [NSDate date];
NSInteger dc = [currentCalendar  ordinalityOfUnit:NSDayCalendarUnit
                                                  inUnit:NSYearCalendarUnit
                                                 forDate:today];

You can this by

NSDate *date1 = [NSDate dateWithString:@"2010-01-01 00:00:00 +0000"];
NSDate *date2 = Your END Date / Today's date may be;

NSTimeInterval secondsBetween = [date2 timeIntervalSinceDate:date1];

int numberOfDays = secondsBetween / 86400;

NSLog(@"No of days passed since new year.", numberOfDays);

Not all days have 86400 seconds (due to DST, leap seconds, etc...). – Catfish_Man Jan 21 '13 at 08:23
