I did find myself still using NSCalendarDate because I wanted its -
dayOfYear method. I wasn't worried about localization because my
application is used by exactly one user in the middle of a cornfield
in SW Michigan. But if someone knows, what is the way to get this
with NSCalendar? I found I could use NSCalendar to get all the other
useful date pieces (such as -dayOfMonth, -dayOfWeek) I needed except
this one. Hmm, I just thought of: computing the first day of the
year and get the interval between the first day and the target day?
I was blinded to that idea I think by the ease of -dayOfYear!
Use ordinalityOfUnit:inUnit:forDate: which is intended to replace the
plethora of methods such as -dayOfYear. You should be able to pass
"day" and "year" as the units.

I am sympathetic to using NSCalendar. At his Boot Camp, Aaron told
me that NSCalendarDate was falling out of favor because it's not a
good player regarding calendars other than Gregorian. I understand
this.
However, the documentation really doesn't provide any direction as
to this for a new developer. You might want to file a bug to make
the documentation push us new developers in the good direction.
Nowhere in the NSCalendarDate docs does it say "don't use this" or
even "try not to use this".
In the very first paragraph of the "Dates and Times Programming
Topics for Cocoa" guide, it says:
"A Gregorian date object, a special type of date object, is useful
for representing dates users do see. It adds methods for converting
dates to strings, converting strings to dates, and retrieving
elements from dates (such as hours, minutes, and the day of the
week). This is implemented by NSCalendarDate in Objective-C and by
com.apple.cocoa.foundation.NSGregorianDate in Java."
( file:///Developer/Documentation/DocSets/com.apple.ADC_Reference_Library.CoreReference.docset/Contents/Resources/Documents/documentation/Cocoa/Conceptual/DatesAndTimes/index.html
#//apple_ref/doc/uid/10000039i )
Not exactly a warning against its use.

Maybe in addition to battling for localization with all of us, you
have to battle with the internal folks too, I don't know. I wish you
the best in your battles :)

Please don't use NSCalendarDate, as it only supports the Gregorian
calendar. Please use NSCalendar instead, unless you still need to
run on 10.3.x.

Given a specific NSDate, I need to be able to find, say, the

hoping to be able to use +dateWithNaturalLanguage with something

myDate.
I know I can brute-force it, by figuring out the myDate's day,
then walking backward and/or forward, but is there an easier
way? One more tried and true, less error-prone, that's calendar-
savvy (not that I'm going to need to go as far back as Oct
1582...)?
Check NSCalendarDate -dayOfWeek and -
dateByAddingYears:months:days:hours:minutes:seconds:
