Prerequisites

Before using harang-calendar, make sure the following are in place.

1. A reachable CalDAV server

You need at least one CalDAV-compatible calendar you can reach over HTTP(S) — for example Radicale, Nextcloud Calendar, Fastmail, or any other server that implements RFC 4791. The plugin only reads from this server; it never writes, so a read-only account is fine if your server supports one. Only Basic Auth is supported — a server that requires OAuth2 instead cannot be used directly.

You will need:

Item	Notes
Server URL	Either the CalDAV base URL or the exact calendar collection URL. The plugin auto-discovers every calendar under the account from either.
Username	Your CalDAV account’s username.
Password	Your CalDAV account’s password, or an app-specific password if your server supports one (recommended over your main account password).

2. Obsidian 1.13.4 or later

This is the plugin’s declared minimum supported Obsidian version. Among other things, it uses Obsidian’s official getLanguage() API (available since 1.8.7) to match its UI language to your Obsidian language setting.

Once both are in place, continue to Installation.
