Travel planning app — best navigation pattern for horizontal scrolling?

I'm designing a trip planning app that allows users to create events under vertical 'Day Columns.' It scrolls horizontally.

However, the 'Day' columns containing events are potentially infinite and it's important for the user to be able to navigate back and forth between weeks (Week 1, Week 2, Week 3).

I'm wondering what you think the best practice is for this problem, and if there are any designs out there that solve a similar problem? Any input would be much appreciated.

You can see my attempt in the wireframe below, but it feels a little awkward. Thanks!
