Calculating difference between 2 dates in years and months in 2 separate fields?

Hi,

I need to be able to calculate the difference between date of birth and date of death in years and months. My issue is that I need the amount of years to be in one field and the amount of months to be in a separate field.

For example, I have the following 2 fields:

BirthDate: 10/11/1994

DeathDate: 2/3/2024

Then somehow calculate this into the following 2 separate fields:

YearField: 29 years

MonthField: 3 months

Is this even possible? I really don't know the first thing about writing javascript from scratch. I've tried searching the forums here for a calculation but my company doesn't allow me to download files from here.
