When setting up an event, in the Gnosis Event Module, you can select either "Single" or "Repeating" for the schedule type. Both types can have multiple days specified for a recurring schedule, but the individual days in the schedule will be treated differently for registrations based on the selection that you choose for the schedule type.
The Single schedule type instructs Gnosis to present the entire event - whether it be one day or multiple days - as a single entry for registration purposes. You would use this option for all once-only events and all events where someone can register once for attending a series of instances over multiple days.
The Repeating schedule type instructs Gnosis to treat each and every instance of the event as if they were individual events for registration purposes. Using this option, someone would need to register for each instance of the event individually if registrations were enabled for it.
Each instance of an event has its own attendance information available to be recorded irrespective of how the registration type is set. Generally, a person will be recorded as attending for each individual event instance - either through the kiosk or via a manual entry in event management.
If the option "Select Attendance Days during Registration" is checked on the event registration setup page for an event with a Repeating schedule type, attendance information becomes a record of the person's intent to attend rather than a record of when they do actually attend. This mode of operation is rarely used and we recommend that you do not select this option unless you have a particular need for this approach.
