Hi, I’d like to add some important technical context to this topic, because the current behavior makes the “day of the week” feature practically unusable on Windows.
Diarium currently reads the Windows short date format to determine whether the day of the week should be displayed. This creates a serious conflict:
If I set the short date format to something like “dddd d.M.yyyy” (so that Diarium shows the weekday),
→ Excel and other applications stop recognizing dates correctly, because the short date now contains text.
If I keep the short date format in the standard numeric form “d.M.yyyy” (so that Excel works properly),
→ Diarium does not show the weekday.
This means users must choose between: a functional Windows/Office environment, or seeing the weekday in Diarium.
Unfortunately, Windows 10 does not allow showing the long date format on the taskbar, so using the long date as a workaround is not possible either.
Because of this, the current implementation is very limiting. Would it be possible for Diarium to: read the long date format instead of the short one, or provide an independent in‑app toggle to show the weekday, regardless of the system’s short date format?
This would solve the issue completely and avoid breaking date handling in other applications.
Thanks for considering this — it would make the feature usable for many Windows users. I should note that Windows 10 is still a supported operating system. And most importantly, this issue must be the same in Windows 11!
