At least something that is legal and that you can be sure that this is the persons will.
What I found weird is that in Germany until 4 years ago “ads” for an abortion was illegal but abortion itself is legal. Under ads it even counted when a doctor posted on their website, that they do abortions. They than changed that law and revoked any conviction until 1990.
Overall when I think how recent some laws changed and what was normal back when I was born or when my parents where born.
Private I use Nextcloud + Betterbird (Thunderbird Softfork (stays compatible with the matching esr version)) + DAVx5 for Android.
At work we use an old web calendar in php5, as this is the only calendar we found that has a side by side view. Each coworker has his own calendar and in the 4 week view, each is displayed side by side. We didn’t found any replacement with that kind of view. Also we use the categories very strict. Each entry need a category, the admin defines the categories and it shows icons for it. Nextcloud even introduced categories a few years ago and still doesn’t have the option to define ones and delete default ones. You can add own categories on the fly, but this is so bad in design, as everyone needs discipline, which doesn’t happen.
