Calculate Sending Birthday Card

[Les_Fenter]

I need a formula for calculating when to send a birthday card that will return a date 10 days prior to the person’s birthday. So if the person’s birthday is 10-10-2019, I want the formula to calculate 10 days prior, or 09-30-2019, returning a date format. Any ideas on that? TIA

Assuming the persons birthday date is in a field called Birthday, put this formula into your Send Card by: field:

DATEADD(Birthday,-10,'days')
