Documentation illustration for Calendar setup. # Calendar setup **Calendars** define when your business can accept appointments. A Calendar can be used by your team when scheduling manually and by the text or voice AI when **Built-in Booking** is selected. Calendars are configured inside the unified **Jobs** workspace; there is no separate Calendars page in the app. ## Getting here In Auto-Respond, open **CRM** → **Jobs**. - To create one, click **Create new calendar**. - To edit one, open the **Calendar** selector and click the edit icon beside its name. Click **Save calendar** or **Cancel** to return to Jobs. ## What a Calendar controls Each Calendar belongs to one business and stores: - A name and display color. - The timezone used to calculate availability and booking slots. - Weekly working hours, including multiple time ranges on the same day. - Appointment length: 30, 60, 90, or a custom whole number of at least 5 minutes. - The customer information the AI must collect before it can book. Create separate Calendars when teams, services, or locations have different working hours or appointment lengths. ## Creating a Calendar Click **Create new calendar**, then complete the three sections. ### Basic information - **Business** - required; determines where the Calendar and its Jobs belong. - **Name** - required; use a recognizable name such as _Estimates_ or _Standard service hours_. - **Timezone** - required and used to calculate working hours and available slots. - **Calendar color** - identifies the Calendar’s Jobs in the combined view. - **Appointment length** - sets the duration of every available slot. ### Availability Under **Weekly hours**, enable the days you accept appointments and add one or more time ranges to each day. For example, set 8:00 AM–12:00 PM and 1:00 PM–5:00 PM to leave a lunch break. A new Calendar starts on Monday to Friday, 8:00 AM–4:00 PM, with the weekend closed. Adjust it to your real hours before pointing a source or agent at it. Only complete slots that fit inside these hours are offered. Past times and times occupied by active Jobs are excluded automatically. ### Information to collect This section controls what the AI asks for before making a Built-in Booking. - **Name** is always collected and cannot be turned off. - At least one of **Phone** or **Email** must be required. - **Address** can be required when the appointment happens at the customer’s location. - Add custom fields for information such as service type, gate code, or property size. Each custom field needs a unique name and description. Unchecked fields are not requested as part of the booking. ## How available slots are calculated Auto-Respond combines: - The Calendar’s timezone. - Its weekly working hours. - Its appointment length. - Scheduled, in-progress, and on-hold Jobs already using the Calendar. Only future slots that fit the full appointment length are offered. Auto-Respond checks availability again when saving, which prevents two people from reserving the same slot at the same time. ## Using a Calendar with Built-in Booking After creating the Calendar, select it in the scheduling settings that should use it. ### Text AI Assistant Go to **Sources** → select a source → **Messaging Settings** → **Conversation Setup** → **AI Assistant** → **Appointment Scheduling**. Enable scheduling, choose **Built-in Booking**, and select the Calendar. ### Voice Agent Open an Agent → **Scheduling** → enable **Appointment Scheduling** → choose **Built-in Booking** → select the Calendar. The AI checks the Calendar’s open slots, collects its required information, and creates a scheduled Job after the customer agrees to a time. ℹ️ A built-in Calendar lives inside Auto-Respond. It is different from choosing a connected third-party calendar as the scheduling service. ## Editing or deleting a Calendar In the Jobs workspace, open the **Calendar** selector and click the edit icon beside a Calendar. Saving changes updates future availability calculations. Deleting a Calendar requires confirmation. Existing Jobs are not deleted, but the Calendar is disconnected from any Sources and Voice Agents that use it. Their Built-in Booking configuration is disabled until you select another Calendar. Scheduled Jobs that retain their dates remain available under **All calendars** with the neutral **Unassigned** style. ⚠️ Before deleting a Calendar, update every Source and Voice Agent that should keep booking appointments. ## Related topics ### [Built-in CRM](https://auto-respond.com/docs/crm/) [See how Calendars connect Leads, Contacts, and Jobs.](https://auto-respond.com/docs/crm/) ### [Jobs](https://auto-respond.com/docs/crm/jobs/) [Use the shared Calendar and List workspace to manage scheduled work.](https://auto-respond.com/docs/crm/jobs/) ### [Text appointment scheduling](https://auto-respond.com/docs/messaging-settings/conversation-setup/appointment-scheduling/) [Configure Built-in Booking for lead conversations.](https://auto-respond.com/docs/messaging-settings/conversation-setup/appointment-scheduling/) ### [Voice Agent scheduling](https://auto-respond.com/docs/voice-agent/scheduling-integrations/) [Configure Built-in Booking for phone calls.](https://auto-respond.com/docs/voice-agent/scheduling-integrations/) *** Questions?
