# Configuring Booking Release Time for Classes and Activities in Go Book

HTML version: [Configuring Booking Release Time for Classes and Activities in Go Book](https://support.gladstonesoftware.cloud/goconsumer/configuring-booking-release-time-for-classes-and-activities-in-go-book)

## Problem
You want a day's classes and activities to open for booking on Go Book at a set time of day, instead of the default class start time, or to change how far ahead sessions are visible.

## Resolution

1. **Set the advance booking period in Plus2**
   - In Plus2, set the advance booking period for each activity and class. This defines how many days in advance a booking becomes available. See [Setting Advance Booking Windows in Plus2](../plus2/setting-advance-booking-windows-in-plus2.md), where 8 = seven days ahead.
   - By default a session opens for booking on Go Book exactly that many days before its start time. For example, a 6pm class with a 3-day advance period is released at 6pm three days before, and a 07:00 class with a 7-day period opens at 07:00 seven days earlier.

2. **Set the booking release offset in the GMC**
   - In the Gladstone360 GMC, go to `Configuration Manager > Configuration > Member Facing Global`.
   - On the **Configuration** tab, open the **Class Configuration** dropdown and set the class release offset (**Midnight Offset (in hours)**) to when you want bookings released, for example 8am, 08:45, or 22:00 the night before.
   - For several sites with different booking rules, use the **All Sites** option to set a separate offset for each site.
   - The offset applies in 360 automatically.

3. **Enable the booking release time in Operator**
   - In Operator, go to `Configuration > Modules > Configure`.
   - Search for **Enable Booking Release Time** and set it to `True` to switch the feature on for Go Book (`False` switches it off).

4. **Change the look-ahead period (if applicable)**
   - In the same `Configuration > Modules > Configure` screen, type **Book Look** in the search box.
   - Increase or decrease the number of days sessions are visible on Go Book (default 14), then save.

## Notes

- The look-ahead period only changes how far ahead sessions are **visible** on Go Book. Customers still can't book beyond each activity's or reservation's own advance booking restriction in Plus2, but it shows future weeks are running, and Go Book shows when a visible session opens for booking.
- Advance booking windows can differ for members and non-members (for example 14 vs 7 days).
- The release offset is documented for classes. If activities, older versions or a specific site do not follow the expected release time, confirm the applicable setting and version with Gladstone Support before changing customer communications.
- Tell customers before changing the release time.
- **Classes still release at the default time:** check **Enable Booking Release Time** is `True` in Operator and the correct offset is set in the GMC.
- **Different sites need different release times:** use the **All Sites** configuration in the GMC to set an offset per site.
- **A session is visible but not bookable:** check the release offset, the Plus2 advance booking restriction and the Operator setting.
- **Prerequisites:** you need permission to change configuration settings in Plus2, the GMC and Operator.
