Oh right, if I assume "date in the past means it's for next year", then
that means that, when the date *does pass*, we won't realize it!
e.g. if Owls says "Dyeable Thru July 15", then on July 14 we'll parse
that as July 15, 2024; but on July 16 we'll parse it as July 16, 2025,
and so we'll think it's *still* dyeable. Under this logic, it's
actually impossible for a limited Dyeworks date to *ever* be in the
past, I think!
I think 3 months is a good compromise: it gives Owls plenty of time to
update, but allows for events that could last as long as 9 months into
the future, if I'm doing my math right.
