Improve handling of dates in languages other than English

Problem: Wikidata does not display dates correctly in many languages. When entering data, it also cannot parse many common forms of dates in other languages. This makes Wikidata difficult to use in other languages. e.g. 1997-02-01 is displayed in Chinese and Japanese as "1 2 1997" instead of "1997年2月1日". When editing, it does not understand "1997年2月1日" even when the interface is in Japanese. In Spanish, it can parse "11 mayo 1961" but not "11 de mayo de 1961". In German it can parse "1. März 2000" but not "1. märz 2000". It can parse "01.02.1997" if the language is Slovak, but not if the language is Czech.
Proposed solution: Display dates using the date format from MediaWiki. Improve the parsing of dates so that it can understand dates written in the usual format for that language.
Who would benefit: Non-English speakers using Wikidata
More comments: This is a long-standing problem which has been proposed here multiple times in the past:

As I was told, phab:T221097 should be fixed in the following days. The bugfix only concerns parsing, though. --Matěj Suchánek (talk) 14:11, 5 February 2023 (UTC)[reply]
Long-standing problem. I can just add two personal experiences with Italian interface: it parses months with lowercase initial (e.g. 22 marzo 2022) but not with less common (but sometimes used) uppercase initial (e.g. 22 Marzo 2022); since in Italy the most-common usage is dd mm yyyy, I can say that dd-mm-yyyy and dd mm yyyy are interpreted correctly, whilst dd/mm/yyyy is interpreted wrongly as mm/dd/yyyy (which can cause errors, if the user doesn't notice the problem when saving). I think this inversion of month and day is a problem perceived also in other languages: probably, in ambiguous cases (e.g. 01/02/2022), the system should just present the two options to the user and ask them to choose, in order to avoid misinterpretations. --Epìdosis 18:46, 5 February 2023 (UTC)[reply]
