What Calendar and To Do solution do you recommend? - programming.dev
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?
On a related note, is it possible to sync all my tasks on Simply (fossify) Calender with a Caldev server. Also does anyone know if there is a good client with Caldev sync on Windows ? I know thunderbird has that functionality, but I would prefer a standalone calender instead of an email client.
I believe you can do this with
DAVx5. I have calendars syncing to fossify with it.

GitHub - bitfireAT/davx5-ose: DAVx⁵ is an open-source CalDAV/CardDAV suite and sync app for Android. You can also access your online files (WebDAV) with it.
