2 date fields in different table
having a calendar table makes your life much easier (because you get to use the time intelligence functions)
you can do those calculations without it but you'll have to write a bit more

Oh sorry, I am not saying that DAX makes no sense but the way I pull my reports, having to always add dates in a table just for that is a huge pain but I understand what you are saying and yes it does make sense.
I will try to do a related between these two and will let you know ;) thanks for your support
Generally, I just create a separate query to whatever my same data source is and just pull in the dates, remove duplicates and presto, a date table, or use DateStream in the Azure Marketplace. I think there is a way to do it automagically with CALCULATETABLE but I would have to confirm that.
