Registration Site connected to events calendar?

Hello everyone! I’m struggling to find anything regarding what I’m trying to accomplish. We have an event registration site for trainings & an events calendar. We’re trying to see if there’s a way to link the two together. The end goal would be when someone tries to select a specific location from a drop down list on the registration, that it opens the events calendar to see what days/times are still available. Is anything like this possible or does anyone have any suggestions to do something similar to this?
