A bunch of calendars only work when connected to the internet. Others don’t sync across multiple types of devices (linux, android, apple, etc).
A lastpass of calendars, but open source.

CalDAV (+CardDAV) is the easiest solution. Evolution mail works great as a desktop client too. DAVx5 will integrate into your android calendar and contacts seamlessly. If nextcloud is to fat for you there is also DAViCal (php+postgres) and radicale (python, file system storage).
Sadly there are no clients that encrypt your data :/
I second this. Would be great if an additional encryption layer was standardized by IETF.
Though if you self-host the calendar e.g. on a Raspberry Pi it does not matter that much whether the data is encrypted or not.
