Only in Preview mode they have. The static values in source view show YYYY-MM-DD for me. It may be possible in the future to change it once they add a setting for it.
Thank you, so much for your input Gino. I’ve found the same thing. Even adding new date values works as expected and keeps the underlying dates in the correct format. It’s only the display as you say. I have also noticed a similar issue in the projects plugin. The date displayed in cards on the board is also wrong, but the actual data is correct.
It’s not a bug : How date and date & time are displayed within Properties relies on your device/OS settings (on Mac you can change those in Settings → Language & Region. No idea how to do so on Windows/Linux though).

I’m on Windows 10. The system has always been set to Swedish regional format with Short date yyyy-MM-dd. Obsidian date properties are nonetheless displayed as MM/dd/yyyy.
I saw several other users reporting the same issues in the various threads. So as far as I can tell, there is a bug.
It’s still a bug. I have English (United States) set as a language but Poland for formats and still seeing dates in this absurd MM/DD/YYYY format. There’s a reason why these things are set separately in system settings.
