It is best to move logic out of the templates and into the code here (among other things, so that it can be tested), so I would change this to return the age in days, instead of just a difference between the two dates. Or you could move the computation into a helper. Either way, it would be good to remove it from the template.
Also, instead of using your own logic to compute the days, you could use
in_days
on a Rails Duration to get the number that you want to display in the UI. Documentation here: https://api.rubyonrails.org/classes/ActiveSupport/Duration.html#method-i-in_daysThere was a problem hiding this comment.

Thanks for the feedback! I will remove the logic from the template and put it into a helper. I won't change age because it is being used in another helper's calculation as is, but make a new age_in_days variable. Thanks for the tip on Rails Duration - will look into that.

in_days doesn't seem to work in the rails console at all. I get an undefined method error.

in_days does not work in the template either. Is there anything I need to do to activate it?

It's fine, you don't need to convert it to
ActiveSupport::Duration
if that doesn't work. The important part is to get the math/logic out of the view, and to add clarity, so e.g. if you leave this method as it is now, consider renaming it toage_secs
(assuming secs is really what it is returning) or at least adding a comment indicating what is this returning.
