<li>%S : day saint (ex: ‘Ste Tabagie, cosmogène’)</li>
<li>%I : day importance (ex: ‘fête suprême quarte’)</li>
</ul>

 [pataphysics-date] : display the current day with the default format <code>%D %d %M %y</code>
<pre><code>[pataphysics-date date="2017-01-28"] : convert a grégorian calendar date to the Pataphysical calendar.
