How to make parametric the New Calculate Column

[Anonymous]

I'm a very very beginner. I just need to create a new column where I want to calculate how many days passed from a date present in a column and the max date present in an another column. 

thanks

@Anonymous ,  New column can not take slicer values. But you can have columns like

new column = datediff([date1],max([Date2]),day)

new column = datediff([date1],today(),day)

Yes, it works as expected and this solved my need. The question now becomes: if the anchorage date would be an "input parameter" and not an information stored in  column ?
