Event cards show wrong dates

Added a similar report to the same issue (I came here to report wrong dates, and saw this one)

Oh wow, this was apparently reported ~2 years ago...

Roderik, thank you for the issue!
We are in the process of releasing a complete new frontend this week! It will be written in Svelte, introducing new features and this bug is then also fixed!
Nico

we have a complete new frontend system deployed today.
this bug is now gone and new features are in place.
you can spot them on drupical.com :)
