When I go to https://ku.wikipedia.org/wiki/Taybet:Agahdar%C3%AE , I see the date in English:
The date string probably comes from moment.js. This library has localization for ku, although the content appears to be in the Arabic script, so perhaps it's better for ku-arab or ckb locale. But in any case, we see it in English, and not even in Arabic-script Kurdish.
What complicates things further is that Moment.js appears to be going into maintenance mode, which may make contributing correct Latin-script localization harder. But if that is done, can the translators at least be sure that it will be used in MediaWiki?
