Hey there @janwidmaier -- great question!

There is no way to automatically tell a single event type to take place at location X or location Y dependent on day, at this time. I’m sorry!

However, there’s a workaround that might suit you well using Calendly Routing Forms!

This might look like: 

• setting up two event types (one for your virtual and one for your in person location)
• setting up a routing form
• asking a question on the form that allows the invitee to indicate what day of week they plan to book
• within the routing form, setting up routing logic that directs an invitee to the correct event type based on day of week they plan to book
• the invitees being auto-routed to the correct event type so no mistakes are made

Alternatively: 

• you can simply create one event type for each location
  • in this case, I suggest including the location in the name of each event
  • i.e. “Meeting: Zoom” + “Meeting: In Person”
• Share Your Calendly Link
• allow invitees to select the correct event type on their own

I hope this helps!
