As an update, since we’ve still been seeing issues around date formatting, so we’re pursuing another fix that should help: If you’re using Planner within Teams, we will default to using the same language/local as Teams.
If you’re seeing this issue persist outside of Teams and your language/locale is set properly for your Office account, please let us know in the comments below!

Just embedded a Planner in Teams for my first experience at using Planner; and have hit this date issue.
Going to make it very painful for us (Australia)
