Tag Calendar

A light, easy calendar for Obsidian. Tag a task, give it a date, and it shows up on the calendar.

- [ ] Send the follow-up email 📅 2026-09-15 #follow-up

That one Markdown line is the whole system. No database, no sync engine, no setup.

Why you'll like it

• One line, one place. Your schedule lives in plain Markdown checkboxes. Edit the line, the calendar updates. Tick the calendar, the line updates.
• One note to manage. The plugin opens a single hub note (_CALENDAR.md by default). Add schedules there, or write the line in any note — both are picked up instantly.
• Copy it anywhere. Press Copy and paste a tag-calendar block into any note — your daily note, a project page, a dashboard. Every copy is live and shows the same data.
• Light. It only indexes lines that carry both 📅 and #follow-up, so it stays fast even in large vaults and never touches your other tasks.
• Recurring, without clutter. Add 🔁 daily, weekly, monthly:15, or yearly:09-15. Completing an occurrence rolls the same line forward to the next date — no duplicated future tasks.

Screens

Compact calendar with a nearest-first list underneath:

Click a day to see everything due that day and tick items off:

How to use

1. Click the calendar icon in the left ribbon. The hub note opens (it's created once if missing).
2. Press Add schedule, or write a line yourself: - [ ] Title 📅 YYYY-MM-DD #follow-up #optional-project-tag
3. Press Copy in the calendar header and paste the block into any other note.

Live block options (all optional):

```tag-calendar
weekStart: monday
showCompleted: false
density: compact
```

Use tag-list as the block name for the list view only.

Settings

Language (English by default; Korean, or follow Obsidian), hub note path, first day of week, show completed by default, default calendar size. A built-in guide with update notes is one click away from the book icon.

Feedback

This plugin is small on purpose, and I keep it that way. If something feels off or you're missing a small thing, open an issue — feedback is folded in quickly.

Install manually

Download main.js, manifest.json, and styles.css from the latest release into <vault>/.obsidian/plugins/tag-calendar/, reload Obsidian, and enable Tag Calendar.

Development

npm install
npm test
npm run build
npm run deploy:local -- C:\path\to\vault

Versions use the date form <year index>.<MM>.<DD> (1.09.15 = 2026-09-15). The community directory requires three-part semver, so a second release on the same day takes the next day number (1.09.16). Edit manifest.json, package.json, and versions.json by hand — npm version normalizes 1.09.15 to 1.9.15 and breaks the release tag.
