Title: {{created:%B %d, %Y}}
Created: 2026-04-12T16:45:29-04:00

<p>
    The <b>&lbrace;&lbrace;created:%B %d, %Y&rbrace;&rbrace;</b> substitution
    parameter references the value of the {{node-link:headers/created}} header
    on a node, and formats the date/time value using an
    <a href="https://www.man7.org/linux/man-pages/man3/strftime.3.html">strftime</a>
    format string in the rvalue portion of the parameter.
</p>

<p>
    For example, this node has the following {{node-link:headers/created}}
    header set:
</p>

<p><pre>Created: 2026-04-12T16:45:29-04:00</pre></p>

<p>
    Here is what the <b>&lbrace;&lbrace;created:%B %d, %Y&rbrace;&rbrace;</b>
    substitution parameter evaluates to:
</p>

<p><pre>{{created:%B %d, %Y}}</pre></p>

<p>
    The format string has a lot of different options. See the
    <a href="https://docs.python.org/3.14/library/datetime.html#strftime-and-strptime-format-codes">Python datetime strftime() reference</a>
    or the
    <a href="https://www.man7.org/linux/man-pages/man3/strftime.3.html">strftime(3)</a>
    man page for further details.
</p>

<p>
    {{node-link:headers/created}} is an optional header. If it is not set on
    the node, then it will cause a build error.
</p>

<p>
    Compare this with the {{node-link:parameters/modified}} parameter.
