I have no problem with this being either in Elpa or Emacs. I was just
reflecting over the problem :).

However, I was thinking yesterday about um-marrying day and month name
strings from hollidays.

Would it be an idea to have those array for names in separate
files from hollidays and maybe shipped with Emacs. I can
machine-generate those for ~200 languages, and they are really small. I
am thinking of a file structure like: "lisp/calendar/locale/". In locale
directory would be one file per language named something like
"names-countrycode.el" (for example names-fi.el, names-sv.el,
names-ar.el etc). A content would be just names of days and
months. Content of each file would like in code belove the email.

Calendar could than just load appropriate file to set localized names
and it could be done when calendar is loaded.

I am not sure if I can extract format string for dates as well.

I had some time today so I did small script to extract this data from
ICU locale databas. As I understand the license, they permit any use of
both data and code:

https://github.com/unicode-org/icu/blob/main/icu4c/LICENSE

I really use just a very small subset of their data from their locale
dir:

https://github.com/unicode-org/icu/tree/main/icu4c/source/data/locales

Unfortunately some of locales are not bit more complicated to obtain, so
I don't have all languages, but quite many.

If we could have database of names for days and months in Emacs, then
only hollidays should need separate packaging.

Would that be something to have? I haven't patched calendar.el yet, but
it shouldn't be difficult to do that, can see tomorrow.
