Thanks for the feedback. Indeed, I tried to make Findings adapt to the user language and preferences, in particular around dates, but I can also see how one would prefer to stick to the Gregorian calendar for the years. I have added your idea of a preference to my list. At this stage, I can’t promise when that will happen, but I sure hope to get to it in the future, and will let you know here.
In the meantime, you can in fact set Findings to run in English, independently of your system preferences, with these steps:
Open Terminal.app (found in /Applications/Utilities)
At the prompt, type the following all in one line (you can copy paste) and press return
defaults write com.findings.Findings AppleLanguages '("en-US")'
Restart Findings, it should now be in English
If you ever need to reset that setting in the Terminal, type the following:
defaults delete com.findings.Findings
Let me know if that solves the issue for you.
