I am not sure where I stand on your calendar, but let me give you another example.
If I had a collection of data (say the results of a scientific experiment or even my organization’s sales number) stored in the “package” as a defined resource (say foo.csv) and the presentation of that information was done dynamically by some set of HTML/CSS/JS that itself represented a resource in the package.
Is that a portable web document? (to you)

If an online calendar is simply a UX over a database then I don't consider it a "document" (whether or not the calendar entries have been curated). But if the calendar system can produce a PDF representation of the calendar, that would be a portable document (but not a "portable web document").
