Service custom booking rules
When to use "On-line available days" rule for specific service?
If some of your services do not follow the same general weekly time table, and only in this case, you can consider to create a specific rule for them in order to represent your real business schedule. It's important to know that every time you add specific rule for your services the whole booking system will slow down due to the large number of calculations required.
Use this option only if really needed.
