availablerecurs

Availablerecurs is a term used in scheduling and calendar software to denote the number of remaining occurrences of a recurring event that are available for scheduling or attendance. It represents the finite capacity of future instances in a recurrence pattern and is used to manage booking and visibility in calendars and planning tools.

In practice, availablerecurs is typically an integer value linked to a recurrence rule. When a recurring event is created with a finite number of occurrences, the availablerecurs is set to that total. Each time an instance is reserved, scheduled, or opened to attendees, the value decreases. A zero value usually indicates that no further occurrences are available. Some systems support unlimited recurrences by using a special value (such as null or infinity) to indicate no fixed end.

The concept helps coordinate capacity and communicate availability. It is used in calendar planning to prevent overbooking, in event registration to track how many future sessions remain open, and in project or resource scheduling to reflect remaining recurring slots. Implementation details may vary, with some platforms tying availablerecurs directly to the number of remaining occurrences, while others compute it dynamically from a recurrence rule and a start date.

Example: a weekly workshop scheduled for 12 sessions starts with availablerecurs = 12. After the first session is reserved, it becomes 11, then 10 after the second, and so on. If a system supports unlimited recurrence, availablerecurs may be left undefined or set to a designated unlimited value.
