# Booking exceptions overview
## What exceptions are for
Exceptions are date-based blocks that prevent your AI agent from booking appointments during specific times. While [business hours](/en/resources/docs/business-hours-settings) define your regular weekly schedule, exceptions let you override that schedule for specific dates or patterns.
Use exceptions when you need to block availability for:
- **Holidays** — National holidays, religious observances, or business-specific closure days.
- **Vacations** — Personal or team time off.
- **Maintenance days** — Office closures, renovations, or equipment maintenance.
- **Recurring obligations** — Annual events, weekly meetings, or any repeating commitment that conflicts with appointments.
- **Partial-day blocks** — Morning-only closures, afternoon training sessions, or any time window you need to protect within an otherwise open day.
When an exception is active, the AI stops offering appointment slots during the blocked time. Customers are not shown those slots as options during booking conversations.
## Accessing exceptions
From the Calendar screen, click the **Exceptions** button in the toolbar to open the exceptions management page:
**https://panel.interlinked-ai.com/en/calendar/exceptions**
This page lets you view, create, edit, filter, and delete all your booking exceptions.
## Types of exceptions
Interlinked supports three types of booking exceptions, each designed for a different scheduling need:
### Single day exceptions
A **single day exception** blocks one specific date. Use this for:
- A one-time holiday or closure
- A single day you know you will be unavailable
- A specific date with a scheduling conflict
Example: Block **October 24, 2026** because of a team retreat.
### Date range exceptions
A **date range exception** blocks multiple consecutive days. Use this for:
- Vacations that span several days
- Multi-day closures (office renovation, travel)
- Conference attendance or extended events
Example: Block **October 24–28, 2026** for a business trip.
### Recurring exceptions
A **recurring exception** blocks a repeating date pattern. Use this for:
- Annual closures (company anniversary, yearly inventory)
- Monthly recurring commitments
- Any date that repeats on a predictable cycle
Example: Block **every January 10** for a yearly company closure.
## Full-day vs partial-day blocking
Each exception type supports two blocking modes:
### Block entire day
When **Block entire day** is enabled (this is the default), the entire day is blocked. No appointments can be scheduled at any time on the blocked date.
### Override hours (partial-day block)
When **Block entire day** is turned off, you can specify a time range to block. Only that specific window is blocked — the rest of the day remains available.
Example: Block **9:00 AM to 11:00 AM on October 24, 2026**. Appointments can still be booked from 11:00 AM onward.
For date range exceptions with partial-day blocking, the same time window is blocked **every day within the range**. For example, blocking 9:00 AM – 11:00 AM from October 24–28 means every day in that range has the same two-hour block.
Tip
Partial-day exceptions are ideal for recurring team meetings, training sessions, or lunch breaks that happen during business hours but are not part of your regular weekly schedule.
## Effect on existing appointments
Exceptions can affect appointments that were **already booked** before the exception was created.
If you create an exception that covers a time period where an appointment already exists:
- The affected customer receives a **cancellation email**
- If you entered a **reason** when creating the exception, that reason is included in the cancellation email
- The appointment is removed from the blocked time
Important
Creating an exception on a date with existing appointments will cause those appointments to be cancelled and the customers to be notified. Always check your calendar for existing bookings before creating exceptions on dates that may already have scheduled appointments.
## How exceptions interact with business hours
Exceptions and business hours work together to determine final availability:
1. **Business hours** define the maximum weekly availability window
2. **Exceptions** remove specific dates or times from that window
3. **Google Calendar events** further reduce availability within the remaining window
The formula for actual availability is:
> **Available slots = Business hours − Exceptions − Existing Google Calendar events**
This means an exception always takes priority over business hours. Even if your business hours say you are open, an exception on that date will block the time.
## Visual indicators
Exceptions are reflected on the calendar with color indicators:
- **Red** — A fully blocked day (entire day is unavailable)
- **Yellow** — A partially blocked day (some hours are blocked, but other hours remain available)
See [Blocked days and calendar colors](/en/resources/docs/blocked-days-and-calendar-colors) for a complete guide to visual indicators and the interactive drawer behavior.
