Yderligere kalenderrelaterede funktioner og problemer i Microsoft Teams til virksomheder

Upon careful review, there is no option to change the date format in Microsoft Planner. The date format itself is actually dependent on what language you’re viewing the page as.
For the workarounds, please check this article: https://www.adamfowlerit.com/2018/07/how-to-cha....
Note: This is a non-Microsoft website. The page appears to be providing accurate, safe information. Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
I hope this helps. Let me know if there's anything I can help.
Kind regards
