Jekyll-Timeago
A Ruby library to compute distance of dates in words, with localization support. Originally built for Jekyll.
Main features:
- Compute distance of dates, in words, ie:
1 week and 2 days ago
,5 months ago
,in 1 year
- Future times
- Out of the box support for
Jekyll
projects, available as a Liquid Filter and as a Liquid Tag - Localization
- Level of detail customization
- Command line utility
- Approximate distance, with customizable threshold, ie:
366 days
becomes1 year ago
instead of1 year and 1 day ago
In fact, jekyll-timeago
started as an extension for the Liquid template engine, to be used in Jekyll and Octopress backed sites. But actually, you can use it easily on any Ruby project and even as a tool from the terminal!

integration in this section.
Installation
Add this line to your application's Gemfile:
gem 'jekyll-timeago'
And then execute:
> bundle install
Or install it yourself as:
> gem install jekyll-timeago
Usage
The gem provides the timeago
method:
Jekyll::Timeago.timeago(from, to = Date.today, options = {})
You can include the method in the current context by including the module (so you can call directly the timeago
method without using the whole scope):
include Jekyll::Timeago
Examples:
>> timeago(Date.today)
=> "today"
>> timeago(Date.today.prev_day)
=> "yesterday"
>> timeago(Date.today.prev_day(10))
=> "1 week and 3 days ago"
>> timeago(Date.today.prev_day(100))
=> "3 months and 1 week ago"
>> timeago(Date.today.prev_day(500))
=> "1 year and 4 months ago"
>> timeago('2010-1-1', '2012-1-1')
=> "2 years ago"
>> timeago(Date.today.next_day)
=> "tomorrow"
>> timeago(Date.today.next_day(7))
=> "in 1 week"
>> timeago(Date.today.next_day(1000))
=> "in 2 years and 8 months"
NOTE If you have the gem installed in your system globally, and you're not using Bundler (probably because you're are writing a basic script), don't forget to require the library first:
require 'jekyll-timeago'
include Jekyll::Timeago
puts timeago('2030-1-1')
Options
locale
To use a different language:
>> timeago(Date.today.prev_day(200), locale: :es)
=> "hace 6 meses y 2 semanas"
>> timeago(Date.today.prev_day(200), locale: :fr)
=> "il y a environ 6 mois et 2 semaines"
Read more about the localization options here.
depth
You are able to change the level of detail (from 1 up to 4, 2 by default) to get higher or lower granularity:
>> timeago(Date.today.prev_day(2000), depth: 3)
=> "5 years, 5 months and 3 weeks ago"
>> timeago(Date.today.prev_day(2000), depth: 4)
=> "5 years, 5 months, 3 weeks and 4 days ago"
threshold
The next component in the time must at least match this threshold to be picked. Set to 0 by default, so you don't get any approximations. Can be used to drop "straggling" values which are too low to be of any use (in 7 months and 2 days
is as good as saying in 7 months
).
>> timeago(Date.today.prev_day(366), depth: 2, threshold: 0.05)
=> "1 year ago"
Localization
By default, jekyll-timego
already provides translations for some languages. You can check the list here. However, you are able to provide your own translations, or even override the originals, easily.
This project uses the mini_i18n gem under the hood to deal with translations. You can read further about all options in its docs. Example:
MiniI18n.configure do |config|
config.load_translations('/path_to_your_translations_files/*.yml')
config.default_locale = :es
end
If you want to contribute and support more default languages, please feel free to send a pull request.
CLI
You can also use jekyll-timeago
from the command line:
> jekyll-timeago --help
> jekyll-timeago 2016-1-1
2 years and 6 months ago
> jekyll-timeago 2016-1-1 --locale fr
il y a environ 2 années et 6 mois
Console
Starts a custom IRB session with the timeago
method included:
> jekyll-timeago --console
>> timeago(Date.today)
=> "today"
Jekyll integration
You have different options to install and use jekyll-timeago
into your Jekyll project:
- Via Jekyll plugin system
Install the gem
to your system:
> gem install jekyll-timeago
In your _config.yml
file, add a new array with the key gems and the values of the gem names of the plugins you’d like to use. In this case:
plugins:
- jekyll-timeago
- Via Bundler
Add this gem to your Gemfile
and run bundle install
:
group :jekyll_plugins do
gem 'jekyll-timeago'
end
Usage
Liquid Filter:
<p>{{ page.date | timeago }}</p>
<p>{{ page.date | timeago: '2020-1-1' }}</p>
Liquid Tag:
<p>{% timeago 2000-1-1 %}</p>
<p>{% timeago 2000-1-1 2010-1-1 %}</p>
Configuration
In your _config.yml
file, you can customize the following options:
jekyll_timeago:
depth: 2
translations_path: '/path_to_your_translations/*.yaml'
default_locale: 'en'
fallbacks: true
available_locales:
- 'en'
- 'es'
- 'fr'
Also, you can set a different language per page using the Front Matter functionality:
---
locale: 'es'
---
