Without a minimum notice window, someone can book you for a slot starting in five minutes — before you've even seen the notification. Setting a minimum advance notice ensures every booking comes with enough lead time to prepare. Here's how in Cal Clear.
Why Minimum Notice Matters
Last-minute bookings catch you off guard, skip your prep, and sometimes arrive after you've already left your desk. A minimum notice period (say, 4 or 24 hours) guarantees breathing room. See minimum notice period for bookings.
Step 1: Open Booking Rules
Sign in to Cal Clear with Google and open your booking link's scheduling rules.
Step 2: Set the Minimum Notice
Enter the least amount of lead time a booking must have — for example, 2 hours for quick calls or 24 hours for prep-heavy sessions. Slots inside that window won't be offered.
Step 3: Save and Verify
Save and open your public page; the earliest bookable slot should now respect your notice window.
Combine With Buffers and Hours
Pair minimum notice with buffer time and working hours for full control. All three are free in Cal Clear.
