# How to Set the First Day of the Week in the TuCalendi Widget

This tutorial explains how to configure the **first day of the week** displayed in the TuCalendi Widget calendar. This option is managed through a **theme template** and lets you adapt the widget's display to your users' **regional standards**.

The **"Week starts with"** field lets you choose between two options: **Monday or Sunday**. The right choice depends on the **country or region** the widget is intended for, since in some markets the week starts on Monday and in others on Sunday.

## Before You Begin

To follow this tutorial, you need to go to the widget's **Appearance** section and either have an **appearance template** ready to edit or create a new one. The complete process for creating and assigning templates is explained in the [general tutorial on how to create and assign an appearance template for the TuCalendi widget](https://www.tucalendi.com/en/s/widget/how-to-customize-the-appearance-of-the-new-tucalendi-widget).

## Step 1. Access the widget's appearance

From the TuCalendi side menu, go to the **"Widgets"** section and select the **"Appearance"** option.

## Step 3. Locate and modify the "Week starts with" field

In the template editor, locate the **"Week starts with"** field. This field is located in the center-right area of the customization panel, next to the **time format** and **date format** options.

Click the field to select the day the week should start on in the widget: **Monday or Sunday**.

The screenshot below shows exactly where the **"Week starts with"** field is located within the appearance editor.

## Step 4. Save the changes

After selecting the day the week starts on, click **"Save"** to apply the settings to the theme template.

## Step 5. Check the element assignment

Once the template is saved, verify that it is **assigned to the corresponding hub or survey with routing**. If the template isn't assigned to any item, the change won't be reflected in any widget.
