# How to convert day of the year to date in ios?

Currently I [failed](https://www.mindstick.com/forum/160484/error-failed-to-launch-debug-adapter-additional-information-may-be-available-in-the-output-window) to [convert](https://www.mindstick.com/forum/2093/configurationmanager-appsettings-convert-n-to-n-why) a [day of the year](https://answers.mindstick.com/qa/39873/what-day-of-the-year-is-known-as-black-thursday-because-on-this-date-the-first-sign-of-the-end-of-the-bull-market-came) [integer](https://answers.mindstick.com/qa/113667/write-code-for-roman-to-integer) to a formatted [string](https://www.mindstick.com/articles/1527/string-split-in-c-sharp) / [date](https://yourviews.mindstick.com/story/3869/propose-day-2024-exciting-date-ideas-for-you-and-your-partner) like **mm-dd**. I tried some different solution approaches, including most of the [solutions](https://www.mindstick.com/articles/12807/product-searching-issues-and-solutions-for-ecommerce-store-advanced-search-autocomplete-suggest) which are posted here - without success.

I expect this: Today is the **359** day of the year - and it should be converted to **12-25**

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

NSDateComponents* components = [[NSDateComponents alloc] init];

[components setDay:359];

[components setYear:2013];

[components setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];

NSDate* day359 = [gregorian dateFromComponents:components];

output

2013-12-25 00:00:00 +0000
