How to create a two day event with one registration?

I’m interested in creating a two day event. I want people to be able to register once and have two days on my calendar be booked. When I try to set up my events, I can’t find a way to link two events to one registration. I don’t want my clients to have to pay twice for the different days. Is there a way to easily accomplish without getting too deep into the code?
Thank you,
