Looking for an offline/online calendar that can sync to multiple devices (lemmy.ml)

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.

You can sync calendars that support CalDav pretty easy to most devices. I am using a Nextcloud instance as server^1 for the calendar and synchronize it to my android phone via DAVx5. GNOME desktop/calendar also has support for CalDav and Lightning (Thunderbird's inbuilt calendar tool) too. For terminal there is khal + vdirsyncer.

^1 some mail provider such as posteo.de or mailbox.org also provide a CalDav calendar for their plans.

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 (webserver+php+postgres) and radicale (python…).

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.

There is EteSync for encryption. But you would need their DAV Bridge for Thunderbird, Evolution, ...

Any cloud-based calendar is what you're looking for. ProtonCalendar is a good one assuming you care about open-source. If you want something open and self-hosted check out Nextcloud / NextcloudPi (run server on a Raspberry pi). Next cloud has a calendar along with a bunch of other useful tools, and it's pretty trivial to get set up for in-home use.

ProtonCalendar. Their mobile app is awesome.

EteSync may be an option.

Fwiw The GNOME Calendar app has served me well. It has syncing capabilities.

The calendar that comes with Ubuntu Touch is also very good - I don't know whether it's available to download to other platforms though.

And there used to be a really nice ToDo / calendar combo, called NitroTasks... but I don't know it's status any more.

OT: Ubuntu Touch is such an awesome mobile OS. The usability and the focus on gestures feels so much more natural than Android. Also the Qt Quick applications fit really well into the environment. I wish it was used more widely.

:) I agree completely.

Tutanota calendar is okay.

It doesn't have offline support.
