I’ve noticed that there are many Dates.Periods available (the ones that you might expect). There are also many functions provided that go along with the Periods. For example, `lastdayofmonth`, `lastdayofweek`, etc. However, we also provide `dayofquarter`, `lastdayofquarter`, `firstdayofquarter`, `quarterofyear`, yet there is no `Quarter` period type.

Is there any reason that the period type was not provided but some associated adjuster functions were?

No reason it wasn’t provided in particular; could definitely be added.

That’s answer enough for me.
