# Sync your own calendars

<PlanNote plan="basic" />

This sync type keeps your own calendars in harmony — e.g. work and personal: events from one automatically block the other. No invite link needed; it runs right after setup.

## One direction or both?

- **One direction** (A → B): one calendar blocks the other, not vice versa. Typical: the personal calendar blocks the work calendar — work stays invisible in personal.
- **Both directions** (A ⇄ B), the **two-way sync**: both block each other. Typical: two equal calendars (two jobs, work ⇄ personal). Counts as **one** sync against your plan limit.

## Setting it up

1. **"New sync"** → **"Sync calendar"**.
2. Choose the **direction**: one-way or two-way.
3. Pick the **calendars** — for a two-way sync, exactly **two writable** calendars (iCal feeds are read-only and can't be a two-way partner).
4. Set the **visibility** — for a two-way sync, optionally **different per direction**: level, [placeholder title](https://docs.kalender-sync.de/en/sync/placeholder-title/) and [all-day behaviour](https://docs.kalender-sync.de/en/sync/all-day-events/) can each be configured per direction ("Per direction →").
5. For one direction, pick the **target** — done. The initial sync starts in the background.

## Good to know

- **No loops**: blockers are never synced back — even in both directions there's no ping-pong ([how sync works](https://docs.kalender-sync.de/en/sync/how-it-works/)).
- **Pausing pauses both directions** — a two-way sync is always paused and resumed as a whole ([pause & end](https://docs.kalender-sync.de/en/sharings/pause-end/)).
- **Three or more calendars** are connected with several syncs — examples under [Multiple accounts & chained setups](https://docs.kalender-sync.de/en/sync/multi-account-setups/).
- Changing settings later: via the three-dot menu → **“Edit”** — sources, target calendar, visibility, prefix and more ([Edit a sharing](https://docs.kalender-sync.de/en/sync/freigabe-bearbeiten/)).
