Regarding the question on TeX.stackexchange I am looking for generally used languages that use different cases for their month and day names.
Based on Czech and Slovak languages I can imagine two cases useful for automatic typesetting of such names:
- Nominative case: report for January 2016 - zpráva za Leden 2016;
- Genitive case: January 5th, 2016 - 5. Ledna, 2016.
- Locative case: report written in January - zpráva napsaná v Lednu
Other cases (14 in total with plural forms) doesn't seem useful for automated typesetting.
Reasoning for this question is: Is it worth embedding this "case sensitivity" to the core package or change in language variants will be sufficient?
