Hi all.

Currently using microsoft products on a work laptop however I'm looking for an open source alternative for a calendar app.

At a min. I would want to it work on android and/or BOTH windows 11 and Linux Mint (so it would cover usage for both partner and myself). I'm a 'plug and play' sort of person when it comes to Linux so nothing too complicated.

If it can sync between devices that would be great but not a deal breaker in any way.

All other functionality is fine to be bare bones, I don't need it to do reminders or send email, just a basic calendar

Any suggestions and thanks all.

*edit. Spelling.

I would reccomend any CalDav compatible Client like Fossify Calendar for Android or Thunderbird for Desktop or anything that comes with your Distro really. Works offline without any special setup.

Syncing is the "tricky" part. If you plan to self host Radicale comes to mind. Otherwise you might want to look into Nextcloud as a service or Etesync for the privacy minded.

Edit: ~~Simple Calendar~~ -> Fossify Calendar

+1 for Simple Calendar (now Fossify Calendar) synced through Caldav - Nextcloud instance

Oh I actually switched to Fossify Calendar a while back. But the old name still sticks... fixed it.

For your laptop, might give Thunderbird a go. It's old school but it still works well.

Cheers. Will have a look!

I use a caldav calendar on my server. Clients sync with it. I use on linux: gnome calendar, windows: thunderbird, android: simple calendar

It really depends on where the calendar itself is hosted and what is responsible for syncing it. There's a bunch of different standards and protocols for syncing calendars and you have to filter apps by what they support.

But if its syncing to Ms365 and you need it to run on windows then Thunderbird is probably your only option. Otherwise there's stuff like KOrganizer or GNOME Calendar.

I have been using calendar.txt for about 2 years now. Works fine and easy to sync.

[–] sxan@midwest.social 4 points 6 days ago (1 children)

We started with plain text. Then everything got more complicated, and everything came with its own incrutable DB. Now we've come full circle: todo.txt, calendar.txt, plain text markup documents[^1].

Some things don't need to be more complex than they are.

[^1]: Some people never left simple and straightforward, but it feels like the Eternal September happened, and fewer people stayed with simple, and now it's getting popular again.

Wait til they find the security enhancements of the analog pen and paper

[–] sxan@midwest.social 3 points 6 days ago (1 children)

Harder to encrypt though, so I question "more secure."

[–] EugeneNine@lemmy.ml 2 points 5 days ago* (last edited 5 days ago)

Harder to backup and synchronize also

DDG it to get a file, else it is quite simple to generate and customize your own. I do it a bit different from the “official” way, but whatever works, very flexible.

Ta. Will have a look. Why would you recommend it?

[–] tisktisk@piefed.social 2 points 6 days ago (1 children)

Encryption is my guess? All tuta recs should include the 3-month requirement It may be less now, but I remember they use to close accounts that were inactive for some small time period
