Enable Calenders in the iCloud settings on both devices via System Preferences. After that your Calenders will sync and your appointments will show up on both devices.

I cannot sinc my iphone calendar with my macbook air. I think I may have two different icloud accounts - how can I change my iphone sign-in so that it matches my macbook air? Thanks.
