Fix Missing Appointment Time Slots in GoHighLevel Calendars

If you manage bookings in GoHighLevel and also organize work in tools like ClickUp, missing appointment time slots on your calendar can quickly disrupt your workflow. This guide explains the exact settings you must check inside GoHighLevel so your available times display correctly on your booking calendars.

The steps below are based on the official product behavior and will walk you through availability windows, buffer times, and other calendar rules that control which slots are shown to your leads and clients.

How GoHighLevel Calendar Availability Works

Before troubleshooting, it helps to understand how the GoHighLevel calendar decides whether a given time slot is shown or hidden. Multiple settings interact together, and if any one of them blocks a time, the slot will not appear.

In GoHighLevel, time slots are generated based on:

  • Your selected calendar availability window.
  • Defined business hours or custom availability.
  • Appointment slot duration and increments.
  • Preparation and follow-up buffers between appointments.
  • Existing bookings and conflicts from connected calendars.

Because of this, even a small configuration change can cause entire blocks of times to disappear from the public booking page.

Common Reasons GoHighLevel Time Slots Are Missing

When time slots vanish from your GoHighLevel calendar widget or booking link, the root cause is usually one of the settings below.

1. Availability Window Is Too Restrictive in GoHighLevel

Each calendar in GoHighLevel has an availability or date range that determines when people can book. If this window is too narrow, time slots outside the range will not appear.

Typical situations where this happens:

  • You limited the calendar to a short range such as “3 days in advance”.
  • The end date for availability has already passed.
  • You chose “date-specific” availability but forgot to include future dates.

To fix this, open your calendar settings and expand the days or weeks in advance that people are allowed to book.

2. Business Hours Do Not Match Your Intended GoHighLevel Availability

Time slots only appear inside your defined business hours or custom availability. If your business hours are set incorrectly, the public booking page will show very few or even no slots.

Examples:

  • Days are marked as “closed” when you actually want to accept bookings.
  • The start time is later than the end time (for example, 5 PM to 9 AM).
  • Your time zone setting does not match your actual working hours.

Adjust your business hours so that each day you want to accept appointments has a sensible start and end time, and verify that your time zone matches your location.

3. Slot Duration and Interval Settings in GoHighLevel

GoHighLevel lets you specify how long an appointment lasts and how often new slots are created. If the duration and interval do not align, some times might never appear.

For instance:

  • You set a 45-minute appointment duration with a 60-minute interval.
  • Your day length is shorter than the total duration plus buffers.

When these numbers conflict, the system may only be able to fit one or two slots per day, or none at all. Use matching or compatible durations and intervals, such as a 30-minute duration with a 30-minute or 15-minute interval.

4. Buffer Times in GoHighLevel Blocking Appointments

Buffer times (before and after appointments) are useful to prevent back-to-back bookings. However, large buffers can unintentionally block most of the day.

Common issues include:

  • Long buffers combined with long appointment durations.
  • Buffers on both sides of the appointment overlapping with your business hours.
  • Buffers that extend beyond the end of your day.

Review your buffer settings and reduce them if they eat into too many potential time slots. Often, a small buffer (for example, 5–15 minutes) is enough.

5. Conflicts from Synced Calendars in GoHighLevel

If your GoHighLevel calendar is connected to external calendars (such as Google Calendar), existing events on those calendars can mark times as busy and remove them from your booking page.

Watch for these cases:

  • All-day events that block the entire day.
  • Recurring meetings at the same time as your appointment slots.
  • Holidays or personal events marked as “busy”.

Check the connected external calendar to see if any events overlap with the missing slots. If needed, change them to “free” or move them so the time becomes bookable again.

6. Minimum Notice and Lead Time Settings in GoHighLevel

GoHighLevel lets you control how soon someone can book before an appointment starts. If the minimum notice is set too high, near-term time slots will disappear.

For example:

  • A 24-hour minimum notice hides all slots within the next day.
  • A long lead time combined with a short availability window can remove almost all options.

Confirm that your minimum notice setting matches your actual policy. If you want same-day bookings, lower the minimum notice to a reasonable amount of time.

Step-by-Step: How to Restore GoHighLevel Time Slots

Use this step-by-step process to diagnose and fix missing appointment times in your GoHighLevel calendar.

Step 1: Open the Correct Calendar in GoHighLevel

  1. Log in to your account.
  2. Navigate to the calendar section.
  3. Select the specific calendar where slots are missing.

Ensure you are editing the right calendar, especially if you use multiple calendars for different teams or services.

Step 2: Check Availability and Date Range in GoHighLevel

  1. Open the calendar’s availability or general settings.
  2. Verify how many days or weeks in advance clients can book.
  3. Increase the range if it is too short.

If your calendar is set to only allow bookings a few days out, extend it so that more future time slots can appear.

Step 3: Review Business Hours and Time Zone

  1. Go to the business hours section for the calendar.
  2. Confirm that each working day is set to “open”.
  3. Adjust start and end times so they reflect real availability.
  4. Confirm the time zone is accurate.

Once updated, refresh your public booking page to see if more slots are now visible.

Step 4: Align Duration, Interval, and Buffers

  1. Locate appointment duration settings.
  2. Confirm the length of each appointment.
  3. Check the time slot interval.
  4. Review buffer times before and after the appointment.

Make sure the total of duration plus buffers fits comfortably inside your business hours. If necessary, reduce either the duration or the buffers.

Step 5: Inspect Connected Calendars

  1. Open your external calendar (e.g., Google Calendar) linked to GoHighLevel.
  2. Look for all-day events or meetings at times where slots are missing.
  3. Change the event from “busy” to “free”, or adjust the time.

After resolving conflicts, sync or refresh the calendar view in your account.

Step 6: Adjust Minimum Notice and Cutoff Rules

  1. Find the section controlling booking notice or cutoff.
  2. Lower the number of hours if you want near-term bookings.
  3. Save your changes and test by viewing the booking link as a client.

If you see more near-term slots after this adjustment, the missing times were caused by an overly strict notice period.

When to Consult Official GoHighLevel Documentation

If you have walked through all the steps above and still cannot see the expected slots, review the official documentation for any product-specific notes or recent updates. The platform occasionally introduces new options that affect how time slots are displayed.
