Suggestion for a full vertical scroll theme

Hello everyone! ??
I hope you guys can give me some advice on a specific theme i am looking for.
I need a theme that has a calendar as main part and could handle events and dates. I don’t relly mind if it’s free or premium.
Basically the idea behind the website would be a sidebar with a full calendar ( with switchable months and years at top and vertical listed days) and the content should (indefinitely) scroll vertically showing the entries linked to the various days, that highlight with the scrolling.
I know this is something both quite easy in the concept but hard to find as already made but every advice would be appreciated ??
Everything that even remotely resembles what i am looking for is good enough for me…I can do some custom work later i suppose ??
thank you.
