# Date + number of days calculation in summary field

Options

Hello, I could use some help in how to write a formula is my summary section where it uses a "Start Date" field from the summary plus a number of days. For example, If the Start Date is 01/01/24 and I want to know what the due date is which is 70 days later. The due date field is also a field in the summary section. Thank you!

I hope you're well and safe!

Try something like this. (Create the Sheet Summary Fields, Start Date, Days, and Due Date)

=IF([Start Date]# <> "", [Start Date]# + Days#)

Did that work/help?

I hope that helps!

Have a fantastic week & Happy New Year!

Best,

Thank you very much. I took your formula example and was able to adjust it slightly without having to add a field for number of days. It's working nicely using: =IF([Start Date]# <> "", [Start Date]# + 70)
