How to Configure Calendar Availability and Buffers
Summary
Calendar availability and buffer settings control when customers can book appointments and how much time is reserved between sessions. These settings are configured per calendar in Calendar Settings and may affect what slots are visible to customers.
Who this article is for
This article is for business owners, administrators, and team members responsible for managing their own or their team's booking calendar availability.
Overview
Before you begin
- Confirm your timezone is set correctly in your business profile before adjusting availability.
- Decide which days and hours you want to accept bookings.
- Determine the buffer time needed between appointments.
- Set a minimum booking notice to avoid last-minute appointments.
Step 1: Open Calendar Settings
Step 2: Set working days and hours
Step 3: Configure buffer time before and after appointments
Step 4: Set the minimum booking notice
Step 5: Set the maximum advance booking window
Step 6: Configure date-specific overrides where available
Step 7: Save and test your availability
Configuration note
Calendar availability is determined by the combination of your configured working hours, buffer settings, external calendar conflicts, and any date-specific overrides. If your external calendar shows all-day events or recurring busy blocks, these may reduce the number of visible booking slots. We do not guarantee that external calendar conflict checking is accurate in all configurations. Always test after connecting an external calendar. Availability behaviour may also be affected by team member settings in round-robin calendars.
Important clarification
A common mistake is setting the minimum booking notice to zero, which allows customers to book with no advance warning. This often leads to appointments appearing immediately with no time to prepare. Another frequent issue is not accounting for timezone differences when setting availability, which can cause slots to appear at unexpected times for customers in different regions.
Resolution guidance
No available slots are visible on the booking page
Check that your working hours are enabled for at least one day and that your minimum booking notice and advance booking window settings are not blocking all visible slots. If an external calendar is connected, check for all-day busy events that may be blocking your availability. Results may depend on your setup, permissions, and active configuration.
Slots are appearing at unexpected times
Verify your timezone setting in your business profile. If your availability is configured in one timezone but the customer is viewing slots in another, times may appear differently. Contact support if timezone behaviour does not match your expected configuration.
Buffer time does not appear to be working
Confirm the buffer time is saved correctly and test the booking flow by booking two consecutive slots. If back-to-back bookings are still possible, verify the buffer direction setting, as some accounts distinguish between pre-appointment and post-appointment buffers. Contact support if this option is not visible.
