Hi, Kenny.
Thanks for your question.
The “/event/MM-DD-YYYY/event-name/” format would probably be problematic if you later activate our PRO add-on because of how it changes the link for recurring events. Here are some examples from our demo site:
I think a better way to accomplish your end goal might be to programatically change the full slug, to something like this: “/event/event-name-YYYY-MM-DD/” (or another format)
It likely wouldn’t be super difficult to hook into save_post_tribe_events (see the Codex) and update the slug with that event’s date.
However, if your event changes its date, then people who bookmark the URL may hit a 404.
If you need some coding help, you may want to ask your developer or reference our documentation and list of known customizers.
