Subtract number from a list of dates

Can I Take a list of dates and subtract from them one number? Like if I have the list: (5/10/2019, 5/17/2019), and this list is the column of a table (let’s suppose Table1 and this table has the column ‘days’) can’t I just do:

Day([Table1].days) - 14 ------->

Inputs: (10, 17) - (14)
Outputs: (-4, 3)
