vdirsyncer VS Radicale

Have a look at vdirsyncer. Sync calendars to a local directory and then use eMacs to read them.

I found vdirsyncer which seems like a nice and promising idea similar to maildir which I already use with notmuch, even though it seems too opinionated and the support for Google calender seems largely untested/unsupported.

For getting ics files, have you seen vdirsyncer ?

On another topic, I maintain a tool to synchronise calendars (e.g.: events and todos) using CalDav (a standard HTTP-based protocol which a lot of calendar servers implement). I'm actually rewriting this in Rust full-time these days.

I used https://github.com/pimutils/vdirsyncer and made a cronjob for it on my host. The configuration is pretty simple - but always do a backup before testing! :)

Whatever CalDAV type calendar you go with (NextCloud and Radicale have been suggested here, Sabre/DAV, DAViCal and Baikal are other options), in case you need to sync calendars to it, you might want to look at vdirsyncer. This way, everyone can keep using his favorite app and you can still gather everything in once central place and have it all synced. Or you get everyone to set up DAVx5.

I have recently started organizing my calendars using `vdirsyncer` [vdirsyncer](https://github.com/pimutils/vdirsyncer)

Hm. Generally for folks who are familiar with the command line I suggest using vdirsyncer, a nifty little python program that lets you keep remote calendars in sync.

Maybe https://radicale.org/ could fit the bill, CalDav for as a calendar server and CardDav for contacts.

I now use CalDAV Synchronizer to sync Outlook to my Radicale CalDAV / CardDAV "server" (a Raspberry Pi), with DAVx running on our phones.

Also look at Baikal, in addtion to Radicale.

Setup: 1. Install a CalDev server on my home server (running Debian Linux) using maybe Radicale (https://radicale.org/) 2. Use the Linux version of ProtonMail Bridge on this server to set up IMAP to connect to this CalDev server 3. Configure filters to automatically forward event invites sent to my ProtonMail address to my CalDev server, decrypted by Bridge 4. Configure my CalDev server to use ProtonMail to send event invites, when I create new events and add invitees 5. Add this CalDev server to Fantastical, using the app on iOS and MacOS as my primary calendar

Caldav is what you are looking for. The other comments mention implementations of them and i can vouch for radicale pretty barebones but does its job

We are thinking of writing a guide to setting up a small Radicale instance. This could be hosted on a raspberry pi, or small NAS or something.

After trying a number of alternatives, I'm strongly recommending radicale.

I used this as a guide, but made some changes to it: https://github.com/Kozea/Radicale/issues/779
