Products / Dates

Perhaps I should explain this a little further:

Imagine a cheese shop, selling particularly mature cheeses. I enter a “date” (in this case a production date), and on the shop front end it outputs an “age” (i.e. a 2 year old brie brie, which if unsold for long enough could become a 3 year old one). The date drives the age so there is nothing to update

I am thinking about using WooCommerce as the backend for a modeling agency. Hence, I want to add “date of birth”, and output “ages” for the ‘products’ (in this case, the models).

Many thanks in advance, Anthony.
