Swipe day to another day

[Somtobro]

I understand there was a controller in the previous versions to achieve this, now it seems in achievable .may be me not seeing the way to go about it. I tried pageview builder and then adding or removing a day proceeding to update the ui. But this approach can't work because it doesn't account for the 31st ..it's gonna to to 32.

I believe there's a way to do it and im not seeing it.would appreciate you all help.thanks
