Created attachment 7854 (screenshot from Xubuntu 18.10 in case links from the post aren't working) Hello. I've noticed that recently Polish pl_PL month names were changed system-wide. Previously "date +%B" command showed current month name as nominative, now it shows as genitive. That's a grammatically correct form when describing date, but it looks strange / bad as a month name here - https://ibb.co/iH2YVe (screen from Xubuntu 18.04) GNOME Calendar - https://ibb.co/jquvbK - and recent Clock panel plugin on Xubuntu 18.10 are displaying it correctly (as nominative), so I think the issue is strictly in Orage. See here - https://ibb.co/kSdJDz Maybe Orage uses "date +%B" everywhere? This may cause that issue.
The orage project is not maintained anymore and has been archived. Closing bugs.
