# Calendars

## Overview

Calendars are used to set up shifts against an asset.

## Creating a Calendar

{% hint style="info" %}
To create a **Calendar**, go to ***Settings > Asset Hierarchy > Calendars***.
{% endhint %}

{% stepper %}
{% step %}
Click **Create**.

{% step %}
Fill in the required fields.

{% endstep %}

{% step %}
Click the **Save and open** button.
{% endstep %}
{% endstepper %}

{% hint style="info" %}
Now you need to create a [Calendar Item](/tillit/knowledge-base/setting-up-tillit/asset-hierarchy/calendar/calendar-item.md) to assign it to specific days of the week and define its validity period.
{% endhint %}

#### Fields

| Name    | Description              |
| ------- | ------------------------ |
| Name \* | The name of the calendar |

### Assigning a Calendar to an Asset

To make use of your shift patterns, you need to assign your calendar to the desired asset.

{% hint style="info" %}
Navigate to **Settings > Asset Hierarchy > Assets**. Then select the relevant **Asset**, locate the **Basic Information panel**.
{% endhint %}

<figure><img src="/files/l13jnMSEunCLhGDoh8ej" alt="TilliT left navigation sidebar highlighting the path Settings > Asset Hierarchy, with &#x22;Assets&#x22; highlighted" width="151"><figcaption></figcaption></figure>

{% stepper %}
{% step %}
Click on the **Calendar field**.

<figure><img src="/files/2bhHAXVZQJiG5m226014" alt="Line 01&#x22; Asset Basic Information dashboard displaying asset details and the Calendar dropdown field highlighted"><figcaption></figcaption></figure>
{% endstep %}

{% step %}
From the dropdown list, select the desired Calendar for the Asset.

{% endstep %}
{% endstepper %}

When you assign a calendar to an asset, TilliT automatically checks whether a shift would currently be running based on the calendar configuration. If a shift is active at that moment, it starts immediately — you do not need to wait for the next scheduled occurrence.

{% hint style="info" %}
This provides instant feedback so you can confirm your calendar configuration is working as expected right away.
