Is it possible to write a scipt to display packages that haven't been updated in X amount of time?

As the title states. I'd like to know if it is possible to write a script which only shows packages which haven't been updated in X amount of time (say 6 months). The reason I'd like a script like this is to check if packages are unmaintained. I am using Fedora 36, but I reckon this would be particularly useful for people using distros that use PPAs (e.g. Ubuntu, Debian), too, since unmaintained packages may pose a security risk. Unfortunately, I do not have the skills to write such a script, but if anyone could prod me in the right direction, I'd be more than happy to try and write it myself.
