Get the future date a number of days from the date in a column in a Pivot Table

Hello, I hope that someone can help me. I have a pivot table which has a column with dates in it (Date A), I wondered if it is possible to create a new column that shows the date 180 days from Date A. Is this something I can use a formula for? If so how do I do it?
Thanks in advance.
