CalDAV2ICS

A script that downloads all calendars from a CalDAV server and caches them locally as static .ics files.

Passwords are never written to disk: the local cache stores only synced calendar data, and credentials are stripped before saving.

Prerequisites

  • Python 3.10 to 3.14.

Installation

pip install caldav2ics

Usage

Create a config .toml file with one section per CalDAV server:

[server_a]
url = "https://caldav.server_a.com/calendar/remote.php/dav/calendars/user/"
user = "user"
save-dir = "/absolute/path/to/calendars/server_a"

[server_b]
...

save-dir must be an absolute path. Run the sync:

caldav2ics config.toml

This prompts for the password. To provide it non-interactively, set C2I_PASSWORD instead:

C2I_PASSWORD=$(cat .password) caldav2ics config.toml

Each server writes a cache.pkl (its synced state, used for incremental updates) and one .ics file per calendar into its save-dir:

calendars/server_a/
    calendar1.ics
    calendar2.ics
    cache.pkl

To integrate with Google Calendar, either upload the .ics files or host save-dir publicly (add basic auth or similar for access control; for stronger security, use a different method).
