Calendar Hub

One calendar, every note from that day — no matter which folder it lives in.

Most calendar plugins map one note per day. Calendar Hub doesn't: click a date and it surfaces every note dated to that day — by the date in its filename or frontmatter — wherever it lives in your vault, so you can find, open, and manage them all from a single sidebar.

Why Calendar Hub?

If you generate a lot of notes — daily logs, meeting notes, AI-generated summaries — they scatter across folders and get hard to track down. A normal calendar only knows about your one configured Daily Note, so everything else stays invisible.

Calendar Hub groups notes by the day they belong to, so a single date can surface many notes at once:

• Daily/2026-05-29.md
• Work log/work log 20260529.md
• Meeting notes/team sync 20260529.md

Click the day, see all three.

Calendar Hub vs. the original Calendar

Calendar Hub is a fork of Liam Cain's Calendar, so everything you expect still works — the monthly view, daily and weekly notes, note-count dots, and "reveal active note." It adds what Calendar was missing:

It uses its own plugin id (calendar-hub), so you can run it alongside Calendar and switch only once you are happy.

Features

• See all notes dated to any selected day (by filename or frontmatter), regardless of folder.
• Open and manage the day's notes from one panel.
• Scan the whole vault or limit matching to specific folders.
• Adjust folder filters directly from the calendar sidebar.
• Match exact Daily Notes filenames and dates embedded inside longer filenames.
• Add extra filename date formats such as YYYYMMDD.
• Use frontmatter date fields as a fallback when the filename has no date.
• Use note-count dots to see how many matching notes exist on each day.
• Keep optional weekly-note support for existing Calendar workflows.

Date Matching

Calendar Hub maps Markdown files to calendar dates in this order:

1. Exact Daily Notes filename match using your configured Daily Notes format.
2. Date embedded in the filename using the Daily Notes format.
3. Date embedded in the filename using any extra formats you configure.
4. Frontmatter date fallback, only when the filename does not contain a matching date.

Filename dates take priority over frontmatter dates. Folder filters apply to both filename and frontmatter matching.

Settings

• Detect daily notes in all folders: Scan Markdown files outside the configured Daily Notes folder.
• Folders to scan for daily notes: Limit matching to comma-separated folder paths. Leave blank to scan the whole vault.
• Date format inside daily note filenames: Add extra comma-separated formats, such as YYYYMMDD.
• Use frontmatter date fallback: Read configured frontmatter fields when the filename has no matching date.
• Frontmatter date fields: Choose fields such as date, daily_date, or calendar.date.
• Note count dots: Solid dots show how many matching notes exist for the day, up to 5 dots.
• Confirm before creating new note: Ask before creating a new Daily Note.
• Show week number: Show week numbers and keep legacy weekly-note behavior.

The folder filter can also be adjusted directly from the calendar sidebar.

Installation

Calendar Hub is available in the Obsidian Community Plugins directory:

1. Open Settings → Community plugins → Browse.
2. Search for Calendar Hub and install it.
3. Enable it, then open the view from the ribbon icon or the Open calendar view command.

Commands

• Open calendar view: Opens the Calendar Hub sidebar view.
• Reveal active note in calendar: Moves the calendar to the month for the active date-based note.
• Open weekly note: Opens or creates the current weekly note when legacy weekly-note support is enabled.

Compatibility

Calendar Hub requires Obsidian 0.9.11 or newer.

The plugin uses Obsidian theme variables and should follow light and dark themes without custom CSS.

Relationship To Calendar

This plugin is based on Liam Cain's original Calendar plugin for Obsidian:

https://github.com/liamcain/obsidian-calendar-plugin

The original project is MIT licensed. The original copyright notice remains in LICENSE, alongside copyright for this fork's modifications.

Calendar Hub uses its own plugin id, calendar-hub, so it can be installed separately from the original Calendar plugin.

Two of Liam Cain's MIT-licensed libraries are vendored unmodified (published build artifacts) under vendor/, each with its license and provenance header: obsidian-calendar-ui 0.3.12 and obsidian-daily-notes-interface 0.9.0. Vendoring keeps the plugin free of runtime npm dependencies.

Development

npm install
npm run build
