Hey Jennifer,
Thanks for reaching out.
The Events Calendar does not generate an actual page, so if you mean that you had a page you made that existed at yoursite.com/events, and then The Events Calendar generated its own calendar at yoursite.com/events, don’t worry: You should be able to just head to Events → Settings in your site’s wp-admin and find an option called “Events URL slug”.
Change this slug to whatever you want. It’s “/events” by default, but you could change it to “/calendar” or anything you’d like.
Save your changes, and now you should see your instance of The Events Calendar is moved to yoursite.com/calendar (or whatever URL slug you specify) instead of that /events URL.
Please let me know if this helps and if there are any other issues or questions I can try to help with!
