Currently, the default when subtracting datetimes is
to break down the duration into multiple parts, months,

From the months piece we can derive years, and from the
days piece we can derive weeks.

But some people have indicated that they'd like something a little

That's true, because you are talking about a DateTime.pm method.
(delta_ymd would make sense in other calendars, that don't have
exactly 12 months.)
However, if DT::Duration is given 'year' units, it should not
automatically convert it to months,

Well, you might, but you can't ;)
I agree completely.
Seriously, I think this idea that DateTime::Duration should work

I was trying to fool around with some calculations from Calendrical
Calculations -- one of the tables in there shows values corresponding
to Rata Die dates, and I was trying to see if DateTime supported
creating DateTime objects from Rata Die values... I didn't see one, so I
guess it doesn't.

Bah, answering my question...
my $rata_die = DateTime-new(year = 1, month = 1, day = 1);
my $from_rd = $rata_die + DateTime::Duration-new(days = $rd_days);

That works, as does:

Hi, dt-ers.
I've been lurking on this list for some time now, and so far I
understand that while a few people have attempted, nobody has come up
with a lunar, solar, or lunisolar calenders (at least I don't remember
seeing it on this list). And so I was just fooling around with some code
to see
A shorter one:
---
my $from_rd =
DateTime-new(year = 1)-add(days = $rd_days);
---
A shorter class for Dave's program:
---
sub DateTime::RataDie::utc_rd_values { @{$_[0]} }
