Harang Calendar

🌐 English | 한국어

📖 Documentation (English / 한국어)

An Obsidian plugin that lets you view events from a CalDAV calendar directly from your notes. The plugin is read-only — it never creates, edits, or deletes anything on your CalDAV server.

Features

• {{hrcal: staged autocomplete — type {{hrcal: and pick an account, then a calendar, then either a date or an event title from one combined list. It inserts {{hrcal:<accountId>:<calendarName>:date:yyyy-mm-dd}} (renders as a widget listing that day's events as cards) or {{hrcal:<accountId>:<calendarName>:event:<uid>}} (renders as an inline chip). Click a chip (or a card in a date widget) to see the full detail popup. You still search by the account's readable name when picking it in the popup — <accountId> is the account's internal id, inserted for you automatically, never typed by hand. Because it's an id rather than a name, renaming an account afterward no longer breaks references you've already inserted; <calendarName> is still the calendar's display name, so renaming a calendar can still break existing references, same as before.
• Calendar view — an agenda list of upcoming events in the sidebar, and a full month grid (with navigation, and click-a-day to see its events) in a workspace tab, both built with Vue 3.
• Multiple CalDAV servers and calendars — configure any number of server accounts; each account is tested and its calendars discovered and individually enabled/colored from Settings.
• Configurable time zone — pick your calendar's IANA time zone or a manual UTC offset per account, used to resolve event times that aren't already UTC.
• Recurring events — RRULE/EXDATE are expanded into their actual occurrences within whatever range is being viewed.
• Follows Obsidian's UI language — Korean or English depending on your Obsidian language setting (via the official getLanguage() API).
• Stale-reference warnings — a date widget warns if the account or calendar referenced by its {{hrcal:...}} reference no longer matches one you have configured (e.g. after a calendar rename, or an account that no longer exists).

Prerequisites

• A CalDAV-compatible calendar reachable over HTTP(S) with Basic Auth — e.g. Radicale, Nextcloud Calendar, Fastmail, or any RFC 4791 server.
• Obsidian 1.13.4 or later.
