Hey @Irving!
Thanks for reaching out.
The “Month View”—and any of the main calendar views—are not widgets, and at this time are not portable and cannot be added to other pages. There is the main /events slug for the calendar on your site, and this is the only place where the main calendar views can exist.
Now, there is a “Mini Calendar” widget, which does look somewhat similar to the Month View. But it is not the same as the Month View, and cannot be made the same as the Month View without an immense amount of code modification and customization far beyond the scope of support. 🙁
If you’re interested in calling this widget via WordPress’ the_widget() function, you can do so like this:
the_widget( 'Tribe__Events__Pro__Mini_Calendar_Widget' );
However, this is much harder to pass arguments to and work with, and so if you need some more flexibility, I would recommend using the widget shortcode instead—no worries, you can still use PHP to generate this by using the do_shortcode() function instead:
echo do_shortcode( '[tribe_mini_calendar category="party"]' );
Learn more about do_shortcode() here and learn more about the widget shortcodes here.
Cheers,
George
