Shortcodes are now a permanent part of the plugin. Therefore, it’s extremely, extremely easy to just manually call the calendar via PHP with the short code. Just use:
<?php echo do_shortcode('[shortcode]'); ?>
And if you want to hide that on certain pages, just use:
<div<?php if (is_page('page-slug')) { echo ' style="display: none"'; } ?>><?php echo do_shortcode('[shortcode]'); ?></div>
Way easier than writing a bunch of code.
