Brand new to Airtable, so forgive me if this is a dumb question. I've shamelessly stolen a formula to calculate start and end dates based off a T- or T+ from a specific event.

Calculated date not an option for Gantt Chart

DATETIME_FORMAT(DATEADD({Calculated End date},{Days Needed to Complete},'days'),'MM/DD/YY')
The dates are calculating just fine, but when I try to add a Gantt view, it doesn't allow me to choose these fields to determine the dates for the Gantt. What do I need to do to have Airtable recognize the output of this formula as a date?

Hi @superdave10, welcome to the community!
The DATETIME_FORMAT function formats its input date as a string, so if you use that function Airtable will not recognize the formula field as a date. Please try using only the DATEADD function, which outputs a Date:
DATEADD({Calculated End date},{Days Needed to Complete},'days')
