This is a plugin for Jekyll that adds ordinals to dates.

prettydate

require 'date'
require 'facets/integer/ordinal'

module Jekyll
  module DateFilter
    def prettydate(date)
      "#{date.strftime('%e').to_i.ordinalize} #{date.strftime('%B')} #{date.strftime('%Y')}"
    end
  end
end

Liquid::Template.register_filter(Jekyll::DateFilter)

To use this the facets gem needs to be installed gem install facets. This file must be saved in the _plugins directory. Then used like so: {{ post.date | prettydate }} Note: This does not work for sites hosted on Github pages as plugins aren't supported.
