For SHTML page
The calendar on the left is called via SSI. To embed this mini calendar, add the SSI tag below to your *.shtml page
where you want the calendar to appear.
<!--#include virtual="month.mini.ssi.php" -->
(1) It is recommended to use PHP Includes than SSI. When SSI is
used, the script will automatically include an iframe for the
mini calendar. For PHP Includes, iframe is not used.
(2) Do not forget to click on the day with MULTIPLE events. You will
see how the events are placed as collapsible items.
