The first message was about recurring dates, like "every Tuesday" or
"Monday and Wednesdays, the 3rd week of each month". ​We have thought about
adding those (there are some bugs about them), but haven't yet.

The second message is about intervals / ranges. We support locale-specific
date intervals, and ranges of other elements (typically numbers), and
elision (when intervening elements are removed, as in "A very … long
message").

We don't support multiple choices for any particular interval/range. If you
have suggestions for improvements...
