Hi there,
Thanks for reaching out.
The original method for having different calendars on your site that was mentioned in that forum thread (using category pages) can work for you. The person that started that thread was experiencing a bug which was why it didn’t work for him. I don’t have access to the video that my colleague shared, but it was a demonstration of how category pages would normally work.
The alternative method would be to use shortcodes but that feature is only available with the premium version of our plugin.
Let me know if you have any other questions.
Best regards,
Marho
