Description

After logging to https://br.wikipedia.org with Edge (version 146.0.3856.84) or Google Chrome or SeaMonkey
when choosing the "Penndibaboù" link (meaning "Preferences")
the "Date format" section is invisible (in the "Neuz" tab, meaning "Appearance")

But if you add ?uselang=qqx at the end of the address for that "Preferences" page
the names of the system messages for that section are shown : prefs-dateformat, datedefault
(prefs-dateformat should display "Furmad an deiziadoù")
(datedefault should display "Dre ziouer")

The same thing happens on the wiki https://br.rodovid.org,
and again it happens only in the Breton language version of that site, not in the English version https://en.rodovid.org (both using MediaWiki 1.39.17)

The issue may be linked to a second problem :

When viewing the Special:RecentChanges link, the names of the months are given with only three letters ("Ebr" for April, "Meu" for March)
but the system messages for the months in the Recent changes are "April" and "March" (not "Apr" and "Mar") so the full names of the months should be displayed.

(Skin makes no difference.)

Aklapper renamed this task from Time formatting section is present but invisible in Special:Preferences of br.wikipedia to Date/Time format section not present in Special:Preferences on brwiki with breton language, works with uselang=en/qqx.Apr 1 2026, 10:12 AM

Aklapper added projects: MediaWiki-Internationalization, MediaWiki-Core-Preferences.

The same problem happens on https://br.wiktionary.org

And there, on the same "Preferences > Appearance" page,

the section for "Skin preferences" is also missing,
but this time ?uselang=qqx does not even show the corresponding system messages.

Submitted a patch to enable the date format section for Breton: https://gerrit.wikimedia.org/r/c/mediawiki/core/+/1278279. It enables $datePreferences and also switches to full month names (F instead of M).

Regarding the missing "Skin preferences" section on br.wiktionary.org, this seems to be a separate issue not related to the language file.
