# Can I Change Booking Time Intervals?

Not yet. Right now, Calendar uses a fixed time grid — you cannot change the interval between available time slots (for example, switching from 30-minute to 15-minute or 60-minute intervals).

## What this means [#what-this-means]

When you create a booking or when [Fuely AI books appointments automatically](https://chatfuel.com/docs/ai-features/how-to-set-up-ai-autobooking), time slots are spaced 30 minutes apart. You cannot change this to 15-minute or 60-minute intervals.

## What you can do now [#what-you-can-do-now]

* **Set service duration** — each [service](https://chatfuel.com/docs/calendar/how-to-set-up-calendar) has a required duration field. When a service is selected for a booking, the end time is calculated automatically based on that duration. This controls how long each booking lasts, but not how the time grid is divided.
* **Set specialist schedules** — you can define [working hours](https://chatfuel.com/docs/calendar/how-to-set-up-calendar) per specialist, including breaks and multiple shifts per day. This limits when bookings can be placed.

## Will this be available? [#will-this-be-available]

Custom time intervals are on the roadmap but there is no release date yet. For now, work with the default 30-minute grid and use service durations to control booking length.
