As an Obsidian power user, I’ve built my entire knowledge management and task tracking workflow around markdown files. The flexibility is unmatched—everything is plain text, future-proof, and fully customizable. However, this approach has one significant limitation: your tasks live exclusively inside Obsidian.
This creates a problem. What happens when you’re on your phone and need to quickly check your todo list? Or when you want to integrate tasks with your calendar appointments? Or when you need to share tasks with family members who don’t use Obsidian?
This is why I created the CalDAV Task Sync plugin—to break Obsidian tasks out of their silo while keeping all the benefits of markdown-based task management.
CalDAV is an open standard protocol for accessing calendar and task data. It’s supported by virtually every major platform and application:
By syncing your Obsidian tasks to CalDAV, you’re not locking yourself into another proprietary ecosystem—you’re gaining universal compatibility.
The most immediate benefit is having your tasks available everywhere. Create a task in Obsidian on your desktop, and it’s instantly accessible on your phone through any CalDAV-compatible app. No need to open Obsidian on mobile (which, let’s be honest, isn’t always the smoothest experience for quick task checking).
Your morning review on your phone, detailed planning in Obsidian on your desktop, and quick task captures on your tablet all work seamlessly together.
CalDAV tasks integrate naturally with calendar applications. This means:
When your tasks live in your calendar ecosystem, you stop context-switching between “what meetings do I have” and “what tasks do I need to complete.”
Many of us already run Nextcloud, Radicale, or use Apple’s ecosystem. Why not leverage what you already have? Instead of adding yet another task management service:
Here’s a powerful workflow pattern: detailed context in Obsidian, quick access everywhere else.
Your Obsidian vault contains rich context: research notes, meeting notes, project documentation, and linked thoughts. Your tasks are embedded in this context with [[wiki links]] to relevant notes.
But when you’re out running errands, you don’t need all that context—you just need the task list. CalDAV sync gives you both:
Not everyone in your household or team uses Obsidian. But they likely use a calendar app.
With CalDAV sync, you can:
Obsidian’s markdown files are already future-proof. CalDAV adds another layer of resilience:
You’re not choosing between Obsidian and CalDAV—you’re using both, each for what it does best.
Let’s be real: typing markdown task syntax on a mobile keyboard is tedious. With CalDAV sync:
CalDAV integration means your tasks work with native OS features:
Your Obsidian tasks become first-class citizens in your operating system.
The CalDAV Task Sync plugin provides bidirectional synchronization between your Obsidian vault and any CalDAV server.
Key features:
[[internal links]] are maintainedConfiguration is straightforward—point it at your CalDAV server (Nextcloud, Radicale, etc.), provide credentials, and the plugin handles the rest.
Here’s how I use this in practice:
The bidirectional sync means everything stays in perfect sync, regardless of where I interact with my tasks.
The plugin is currently in early development and requires installation via BRAT (the Obsidian beta plugin manager).
Installation steps:
Rockockoronkorock/obsidian-tasks-caldavNote: As with any sync plugin, backup your vault before initial sync. The plugin is under active development, and testing across all CalDAV providers is ongoing.

Obsidian’s markdown-based approach to tasks is powerful for deep work and knowledge management. CalDAV’s universal compatibility makes tasks accessible anywhere. Together, they create a workflow that combines the best of both worlds:
The CalDAV Task Sync plugin bridges these two worlds, letting you work the way you want, where you want, without compromise.
Your tasks deserve to be as flexible as your notes—give them the freedom to sync.
