Say you have a Date field called "Effective Date". And you want to have another Date field that is "Expiration Date" that will always automatically be 30 days after "Effective Date." There is a very easy way to do this using Formula fields and the DATEADD function.

Below, we'll walk through creating a Date field called "Effective Date" and a formula field called "Expiration Date" where "Expiration Date" is automatically always 30 days after "Effective Date." You can repeat this process for any number of Date fields and number of dependent Formula fields that you like. The sky's the limit! 🚀
​

Here we'll just create a regular Date field and specify a format for it.

When creating the "Expiration Date" field, instead of selecting "Date" as the field type, select "Formula." Then in the formula input box type:

DATEADD({Effective Date}, 30, "days")

This will tell Woodpecker to automatically add 30 days to whatever the "Effective Date" is. You can learn more about the available options for the DATEADD function here.
