Find Files Created Today

I would like to find files created today. I created some files using a poorly-documented program I purchased but do not know where they are located due to the lack of documentation. Please do not tell me to use spotlight. I have found that to be useless as it does not find the files. Something I could do with terminal would be best. I do not know what folder the files would be in so the search would need to cover the entire hard drive. I am using OS Mojave.

I click Post and it says Please choose a Topic? WTF?
