# Create your first sharing

A **sharing** connects source calendars with a target. You start one from the dashboard via **"New sync"** (in the sidebar: "New synchronization") — after that you are guided through the setup step by step.

Prerequisite: at least one [connected calendar](https://docs.kalender-sync.de/en/getting-started/connect-first-calendar/). To link your own calendars you need two writable calendars (possibly from two accounts).

## Step 1: Choose the type

<Frame src="/images/app/en/wizard-type.webp" alt="Step “What would you like to set up?” with the cards “Share calendar” and “Sync calendar”" caption="The first step: share your calendar or sync your own calendars." />

You can choose between two paths:

- **Share calendar** — your availability goes to another person. They receive an invite link and choose their own target calendar.
- **Sync calendar** — you link two of your own calendars, one-way or both ways (available on Basic and up). No invite link needed. (Details: [sync your own calendars](https://docs.kalender-sync.de/en/sharings/self-sync/) — this article follows the sharing path.)

## Step 2: Pick calendars

Select one or more **source calendars** — across all your connected accounts. All busy times from these calendars flow into the sharing combined.

A calendar missing from the list? Via **"Connect calendar"** you can attach another account right there; your progress is kept.

## Step 3: Set visibility

<Frame src="/images/app/en/wizard-visibility.webp" alt="Step “Visibility” with the levels Busy only, Title + time and Full details plus preview" caption="The three visibility levels — the preview on the right shows what the receiving side sees." />

Now you decide what the receiving side sees:

| Level | Description |
| --- | --- |
| **Busy only** (default) | Only that you're busy — no details |
| **Title + time** | Event name plus start and end time |
| **Full details** | Incl. location, description, notes and links |

All details on the levels and what is never transferred: [Visibility levels](https://docs.kalender-sync.de/en/sync/visibility-levels/).

Two optional fine-tunings at this point:

- **Placeholder title** (Basic and up, with "Busy only"): your own text instead of the default "Geblockt" — e.g. "Busy" or "Private".
- **All-day events**: by default they are **treated as free** (birthdays and public holidays won't block a whole day). You can choose "Block the whole day" instead. More under [All-day events](https://docs.kalender-sync.de/en/sync/all-day-events/).

Attendee lists and third-party data are never transferred — regardless of the level.

## Step 4: Send the sharing

Finally you create the sharing and invite the receiving side — via a copyable **invite link** or directly **by email**. The link is valid for **7 days** and single-use.

In the dashboard the sharing shows as **"Pending"** until the invitation is accepted — what the receiving side sees is covered in [I received an invitation](https://docs.kalender-sync.de/en/getting-started/received-invite/). After that the status switches to **"Active"**.

## After setup

- The **initial sync** runs in the background and can take a few minutes depending on the number of events (up to half an hour for large calendars). You'll receive an email once it's complete.
- The synced range is **3 months into the past; into the future depending on your plan: 6 months (Free & Basic) or 18 months (Professional)** — older and more distant events stay out ([sync window](https://docs.kalender-sync.de/en/sync/sync-window/)).
- From then on, changes flow automatically: almost instantly for Google/Microsoft on Basic and up (every 30 minutes on Free), every few minutes for Apple/KSuite/iCal feeds ([How sync works](https://docs.kalender-sync.de/en/sync/how-it-works/)).
