Migration 2014.04.12

NSDate+TimeAgo has merged with DateTools. DateTools is the parent project and Matthew York is the project head.

This project is now part of DateTools. Please visit https://github.com/MatthewYork/DateTools

This repo is here in archive form. New work should be contributed to DateTools.

2016.01.04. To reiterate, all issues and contributions should go to DateTools, there is zero promise anything here will be looked at. Kevin's attention is on Kerf.


This is an iOS, Objective-C, Cocoa Touch, iPhone, iPad category for NSDate. It gives NSDate the ability to report times like "A moment ago", "30 seconds ago", "5 minutes ago", "Yesterday", "Last month", "2 years ago", and so on.

This functionality has variously been referred to as a "time ago", "time since", "relative date", or "fuzzy date" feature.

NSDate+TimeAgo currently supports the following languages:

  • en (English)
  • ee (Estonian)
  • es (Spanish)
  • zh_Hans (Chinese Simplified)
  • zh_Hant (Chinese Traditional)
  • pt (Portuguese)
  • fr (French)
  • it (Italian)
  • ru (Russian)
  • de (German)
  • nl (Dutch)
  • hu (Hungarian)
  • fi (Finnish)
  • ja (Japanese)
  • vi (Vietnamese)
  • ro (Romanian)
  • da (Danish)
  • cs (Czech)
  • nb (Norwegian)
  • lv (Latvian)
  • tr (Turkish)
  • ko (Korean)
  • bg (Bulgarian)
  • he (Hebrew)
  • ar (Arabic)
  • gre (Greek)
  • pl (Polish)
  • sv (Swedish)
  • th (Thai)
  • uk (Ukrainian)
  • is (Icelandic)
  • sq (Albanian)
  • sk (Slovak)
  • ms (Malay)
  • km (Cambodian)
  • id (Bahasa-Indonesia)
  • mn (Mongolian)
  • ur (Urdu)

If you know a language not listed here, please consider submitting a translation. Localization codes by language.

This project is user driven (by people like you). Pull requests close faster than issues (merged or rejected).


  1. Add the files to your project - manually or via Cocoapods (pod 'NSDate+TimeAgo')
  2. Import the header using #import "NSDate+TimeAgo.h"
  3. Call the timeAgo method in the following way:

NSDate *date = [[NSDate alloc] initWithTimeIntervalSince1970:0]; NSString *ago = [date timeAgo]; NSLog(@"Output is: \"%@\"", ago); 2011-11-12 17:19:25.608 Proj[0:0] Output is: "41 years ago"

2 other methods are available:

  • dateTimeAgo: returns times with only strings of the type: "{value} {unit} ago"
  • dateTimeUntilNow: returns only "yesterday" / "this morning" / "last week" / "this month" -- less precise than dateTimeAgo but more natural

Those three methods can be interchanged as they have the same signature.

Future Directions

Would be nice to

  1. add customization options (e.g., should it report seconds or just "a minute ago")
  2. add string customization
  3. have more localizations
  4. make dateTimeUntilNow more precise: instead of "Last week" use "Last Friday", "Last Monday" etc.
  5. other
