Block Masters. I humbly come before you to seek aid in obtaining ideas for names of months that may or may not come up in my homebrew world of Lisney Dand*
I've gotten it set up similar to the Fearun calendar 12 months 30 days each, 10 day weeks. I was thinking of tacking on 4 extra days as specific Holidays/feasts also to separate the seasons. Weather or not its its own "month" or just a special day i'm not sure yet. So 364 days total iirc. No week day names.
I was doing a mix of languages for the months. (thanks G Translate!)
Here are a few randomly generated ones that I made that I think could fit into the scheme that you already have. Eillarr Chourr Thiirnor Himfrerlar Ulberdim Shymtrun Corthin Shystaern Zemmor Thandost Oyindlyrbar Kondul
