A minimum notice period is the least amount of lead time a booking must have. It stops someone from grabbing a slot that starts in ten minutes — before you've even seen it — so every appointment comes with room to prepare. Cal Clear enforces it automatically.
What It Prevents
Without a notice window, bookings can appear with no warning: after you've left your desk, during focus time, or before you can prep. A minimum notice guarantees a predictable runway to every meeting.
Choosing the Right Window
- 2–4 hours — quick calls and flexible schedules
- 24 hours — sessions needing preparation or materials
- 48+ hours — high-touch engagements or travel
How Cal Clear Enforces It
Set your minimum notice once and Cal Clear removes any slot inside that window from your booking page — so it's simply not offered. Pair it with buffers and working hours for full control. See how to limit advance notice and buffer time.
A Quiet Anti-Spam Benefit
Removing instant-booking slots also deters impulsive and abusive bookings. See preventing appointment spam. It's free in Cal Clear.
