Flow to choose date from list

I want to make a flow with which i can pre-specify a list with dates, and then that it returns the first date from the list that is today, or after today
I want to save that date as a tag, of virtual device, or anything like that, so that i can add it on my dashboard.

Does anyone have tips with what the easiest method would be to achieve this?

Check out the Better Logic Library app.
It’s has lots of time & date possibilities

I did have a look at that, but have not been able to piece together a solution bases on that. Any tips?
