What Calendar and To Do solution do you recommend?
I would like to have a central Calendar that I could sync everything to it, from my email calendars and my to do list, is there something like that selfhosted or not, that is FOSS?
I use Radicale for my calendars, reminders, and contacts precisely because of how minimal it is. It has been very reliable for me and is very easy to back up and restore since it is just files.
