This field deducts 130 weeks from the "Date" field, does this look right?

If so, the formula is

And so you can try:

thank you for your reply, unfortunately it still not working.  I want to calculate the due date by taking the season start date field (MM/DD/YYYY) and subtracting a number of weeks (-130, -53, -35) for each record to come up with the due date. Does Airtable formula not recognize my field # wks -130 ( or any number of week) and able to subtract that number of weeks from the season start date?  

Hi,
The second @TheTimeSavingCo formula should work. Formula must include information - which unit you want to add/subtract, so instead of 'date' you should type 'week' or 'weeks'
Also, you should remove minus, otherwise you get   Date  -(-130) weeks  so it will add weeks instead of substract.
Of course, you should insert your field names,  Season Launch, Weeks from launch

I adjusted the formula in these two version and getting problem message and then #error? 

Could you try creating a new formula field and pasting the following formula in?

Use this formula for milestone dates:

DATEADD({Start Date}, {Number of Days}, 'days')

Or, to exclude weekends:

WORKDAY({Start Date}, {Number of Days})

To understand anything that contains a circle, use pi.
