<!-- Now we can run the date through a filter to get the desired format. -->

<!-- date_to_long_string -->

{{ page.date | date_to_long_string }}

<!-- 23 March 2016 -->


<!-- date_to_rfc822 -->

{{ page.date | date_to_rfc822 }}

<!-- Wed, 23 Mar 2016 23:20:00 +1300 -->


<!-- date_to_string -->

{{ page.date | date_to_string }}

<!-- 23 Mar 2016 -->


<!-- date_to_xmlschema -->

{{ page.date | date_to_xmlschema }}

<!-- 2016-03-23T23:20:00+13:00 -->


<!-- date -->

<!-- date gives us complete control of the format. We can specify a template of the format we want. For example. -->

{{ page.date | date: "%m/%d/%Y" }}

<!-- 03/23/2016 -->

<!-- or -->

{{ page.date | date: "%-d %B %Y"}}

<!-- 23 March 2016 -->

<!-- There’s many placeholders we can use for date formatting. -->

<!-- One notable exclusion from this list getting the ordinal date. For example we couldn’t output “May 23rd” because there’s no placeholder for the “rd”. -->

<!-- A workaround for this is to use Liquid to calculate and output the ordinal. -->
