|The CLDR has: | | <calendar type="gregorian"> There is also CLDR-as-JSON now, on, well, at least Github[1]. Officially that is! Thanks to the Unicode people for that, even though it doesn't seem i will ever need that as a programmer, i once asked them for JSON, and now there is. E.g., "dates": { "calendars": { "gregorian": { "months": { "format": { "abbreviated": { "1": "янв.", "2": "февр.", "3": "мар.", "4": "апр.", "5": "мая", "6": "июн.", "7": "июл.", "8": "авг.", "9": "сент.", "10": "окт.", "11": "нояб.", "12": "дек." }, [1] https://github.com/unicode-cldr/cldr-dates-full/tree/master/main --steffen
