Hmm... I've taken a look at the format_recurrence and other code in the test.
Your proposed solution will work fine if I trust my content contributors to
define recurrence patterns in a meaningful way out of the gate... but what if
they add each event occurrence as a discrete date -- even though it follows a
pattern; e.g. they enter every Friday in March as a separate date rather than
specifying a recurring event by week with dow = Friday bounded by 3/1 and 3/31.
More likely, they might enter a series of dates not realizing that the dates
even follow an established pattern.
I guess what I'm looking for is some code to take an arbitrary list of dates
and a prioritized list of pattern types (e.g. I would prefer to display by
"weekly by day of week" if such a pattern can be found in these dates) and to
then search for a combination of those patterns within the supplied list that
results in 100% coverage while minimizing complexity... then would I apply the
ICAL to human sentence parser...
In retrospect, this might make a good CS dissertation; probably a bit on the
complex side.
In the near term, I might be better off just custom coding a small set of
acceptable date presentations, e.g. month / list of days or span of days in
month when event occurs / times when event occurs on those days, and be done
with it; such as Jan 1-5, 8-12, and 27 at 3:00 p.m. and 4:30 p.m. instead of
"Weekdays in the first two weeks in January as well as the 27th of January at
3:00 p.m. and 4:30 p.m."

DateTime::Format::Natural is the place to implement this, but it isn't
finished yet.
DateTime-Format-ICal provides an ICal text output, which is structured
enough to be parsed&formatted into human-readable sentences.
There are some examples of the ICal output here:
