Month names collection / metastudy

[Juan_Sali]

An interesting find. It's dated c. 1450-1465, so just a little bit late - for some.

You've called this new Latin, but where does it come from? Back in earlier investigations, I looked at a lot of liturgical calendars, some of them Latin, and "aberel, aberil" didn't show up in the 'old' Latin. How did it get to the 'new' Latin??

Perhaps I didnt express myself well. Old names (in german) along with new names (taken from latin).
