--2024-mm-01|ru}} – nominative – genitivewhere 'mm' is a month number (1–12)
That seems to be nonsense because the actual format strings are 1 and 2 bytes only.
'a-m' and 'n-z' work but not if this module is invoked one right after the other.
mw.language:formatDate won't work for this application because it does not accept (so far as I can tell fromthe documentation) a language parameter; does.
See [Phab:T299909] and especially the linked discussion. In essence, accumulates length of formatstrings for each call on a page. When that number exceed 6000, returns an error message. So, thismodule must be d only once per page.
All 12 months of the year must be tested because some languages that have different 'F' and 'xg' month-names alsohave same-named months for 'F' and 'xg'.
How to know that the languages discovered by this module really do use 'xg' for genitive dates?
