This determines when and for how long publishers can book slots. ## Configuration options Configure behavior settings such as the minimum number of participants required per booking, automatic confirmations, and registration parameters. ## Ask additional questions Coordinators can define custom questions that publishers must answer when booking a slot, such as safety checks or route selections. ## Defining bookable items Add and manage bookable items, such as specific carts, locations, or literature stands, that publishers can choose during reservation. ## How to create a booking / reservation Publishers can navigate to the public calendar view, select a free date and flexible time range, choose their cart or item, and optionally invite partners to join their booking. ## Recurring Bookings [Open Settings](https://calendar.pw-tools.net/admin/kalender/2) To save time, publishers can schedule reservations that repeat on a regular weekly interval. ### Weekly Recurrence Rules **What it does:** When enabled by the administrator, publishers can select a checkbox to make their reservation repeat weekly.
