Custom Time Slot Intervals

Time slot intervals determine how available start times appear on your booking page. Use them when you want invitees to see starts every 15 minutes, every 30 minutes, or at another fixed spacing.

What Are Time Slot Intervals?

The interval controls the spacing between bookable start times. For example:

• 15-minute interval: 9:00, 9:15, 9:30, 9:45, 10:00...
• 30-minute interval: 9:00, 9:30, 10:00, 10:30...
• 60-minute interval: 9:00, 10:00, 11:00, 12:00...

The interval is independent of meeting duration. A 30-minute meeting with 15-minute intervals still lasts 30 minutes, but invitees may be able to start at 9:00, 9:15, 9:30, and so on.

Available Options

Common interval choices:

Sync with Duration

Choose Use meeting type duration (default) to automatically match the interval to the meeting duration:

• 30-minute meeting: 30-minute intervals
• 60-minute meeting: 60-minute intervals

This keeps starts aligned with the meeting length and is a good default for structured schedules.

Examples

Short Consultations

For 15-minute quick calls:

• Meeting duration: 15 minutes
• Time slot interval: 15 minutes

Available slots: 9:00, 9:15, 9:30, 9:45...

Standard Meetings

For 30-minute meetings:

• Meeting duration: 30 minutes
• Time slot interval: 30 minutes

Available slots: 9:00, 9:30, 10:00, 10:30...

Flexible Scheduling

For 45-minute sessions with maximum flexibility:

• Meeting duration: 45 minutes
• Time slot interval: 15 minutes

Available slots: 9:00, 9:15, 9:30...

This allows attendees to start at various times while the meeting still takes 45 minutes.

How Intervals Interact with Availability

Availability Window

If your availability is 9:00 AM - 12:00 PM:

The last visible slot must still leave enough time for the full meeting duration inside your availability window.

Buffer Times

Buffers can reduce available slots. With a 30-minute meeting, a 15-minute buffer, and 30-minute intervals:

• 9:00 available
• 9:30 blocked (buffer from 9:00 meeting)
• 10:00 available

See Understanding Buffers for more details.

Best Practices

Match Your Workflow

• Back-to-back meetings: use intervals that match your duration.
• Need prep time: use buffers instead of longer intervals.
• Flexible timing: use smaller intervals, such as 15 or 30 minutes.

Consider Attendee Experience

Smaller intervals give invitees more choices, but they can make the booking page feel busier. Larger intervals are easier to scan, but less flexible.

Account for Time Zones

Standard intervals such as 15, 30, and 60 minutes are usually easiest for international attendees to understand.

FAQ

Does the interval affect meeting duration?

No, interval and duration are independent. A 30-minute interval with a 60-minute meeting still books 60-minute appointments. They just start on the half-hour.

Can I have different intervals for different meeting types?

Yes, each meeting type has its own interval setting.

What's the minimum interval?

5 minutes is the smallest option in the interval dropdown.

Why don't I see slots at certain times?

Even with small intervals, slots won't appear if:

• Another meeting is already booked
• Buffer time blocks the slot
• The slot doesn't leave enough time for the full meeting
