Hi Diana,
Thanks for reaching out!
With The Events Calendar, you have pages with calendars for your each of your event categories. You can go to Events > Categories and hover over the category name, then click “View” to see these pages. I would recommend taking a look at this post for some good information on using event categories.
Events Calendar Pro offers a bit more flexibility with displaying calendars around your site, including widgets and shortcodes. You can use these to display mini calendars or full calendar views by category on different pages.
Please let me know if you have any more questions!
Thanks,
Jennifer
