Hi and thanks for getting back to me.
What I wanted to achieve was the booking calendar showing 30 minute increments i.e. 9.00 9.30 10.00 10.30 etc. regardless of the service duration. So even if a service was 90 minutes, the calendar would still show appointment times in 30 minute ‘slots’ on the calendar. At the moment, the calendar only shows timeslots based on the duration of the service starting from the beginning of the working hours.
