In Cal ID, the Minimum Notice setting gives you the lead time you need to prepare, so you never get surprised by a meeting that appears on your calendar at the last second.

​
Setting a minimum notice

This setting prevents bookers from taking a slot that is too close to the current time. For example, if you set a 2-hour notice, no one can book a meeting with you that starts less than 2 hours from now.

​
Why use a minimum notice?

  • Avoid surprises: Stop meetings from “popping up” on your calendar while you are already busy or away from your desk.
  • Preparation time: Ensure you have enough time to review notes or research an attendee before the call starts.
  • Schedule peace of mind: Know exactly what your day looks like without worrying about last-minute changes.

How it looks for the booker

  • If it is currently 2:00 PM and you have a 1-hour minimum notice, the booker will only see available slots starting from 3:00 PM onwards.
  • Any slots between 2:00 PM and 3:00 PM will be automatically hidden, even if you are technically “free” on your calendar.
If you have a busy morning, consider a 12-hour or 24-hour notice. This ensures that when you wake up, your schedule for the entire day is already set and won’t change unexpectedly.

​
Why today’s slots may still not appear

A short minimum notice (for example, 1 minute) does not guarantee that same-day slots will show on your booking page. Other settings and calendar state can hide today entirely. If bookers see the next available day as tomorrow, check the following in order:
  1. Availability schedule — confirm today’s weekday is toggled on with working hours that still have time remaining. See Create an availability schedule.
  2. Date overrides — a date override for today that marks you unavailable takes priority over minimum notice.
  3. Buffers and existing events — buffers added before or after events, plus meetings already on your connected calendar, can consume the rest of today’s remaining time.
  4. Show only the first slot of each day — if First Slot Only is enabled and today’s first slot has already passed, no other slot for today appears.
  5. Time-slot intervals — a time-slot interval larger than the time left in today’s working hours can leave no valid start time for today.
  6. Booking frequency limit — if a per-day booking frequency cap has already been reached for today, remaining slots are hidden.
