Calculating a baby's age in days, months, years?

I have discovered how to use the Calculation widget to determine age in days or in years.

But I need to calculate age in days, months, and years. I need to know that a person is 14 days, 3 months, 1 years old, for example.

How can I achieve this?

Following the instructions in this guide — Mastering-Date-and-Time-Calculation

I was able to create this Sample Form that I believe meets your requirement.

I would suggest that you create a clone of that Sample Form in your account so you can inspect it.

Normally, only the Birthday field is shown on the form and the text below will appear conditionally when the Birthday field is filled. But for testing purposes, I did not hide the other fields yet.

If you have other questions or concerns, please feel free to let us know.

I've copied your code exactly, but it doesn't seem to work.

Solved. Thank you.

I discovered you have to click 'save' to save the code in a Form Calculation Widget. It does not save automatically!
