Good evening Ryan and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
Is there a way to add a button to an event page that will take them back to the month that they were viewing?
The short answer is yes. In fact you can customize pretty much any view to your liking (adding buttons, moving stuff around, etc..).
You might want to read our Themer’s guide to get a sense of how that works.
Let me know if that helps.
Have a great day!
Geoff B.
