That's wrong in two ways, yes.
The Date class isn't inside a module and require is used to pull in files, not modules (though those exist in files)
It's common that people get this kind of stuff wrong all the time and often only try to say things approximately right. Usually if you know exactly what happens then you'll get most of the terminology right as well. It's important to only trust select sources on the finer details of terminology, codecademy certainly isn't such a source.
To further add to the confusion plenty of languages use similar concepts and similar terms but not always mapping between those the same way or being subtly different.
