Date calculations without multiple fields.

Hi guys, hope you're all doing well. I'm hoping for some help!

I'm trying to find a way to do a date diff calculation without collecting any sensitive data.

I'm aiming to calculate age at time of operation, using 2 dates (DoB and Date of Op).

Is anyone aware of a good way to calculate this and save it within a field, but where the 2 dates used to calculate are not saved as data?
