About Calendar data instances

Use this data class to define the business days and holidays for an organization. Calendar data instances can be referenced in organization, work queue, and Operator ID data instances, and in service-level agreements.

The following tabs are available on this form:

If your application and business operations depend on business day calculations, be sure to create calendar instances in advance for each future year (and every district, country, or jurisdiction) needed by your application. Business calendar functions such as isBusinessDay() fail with a Java exception when a date more than one year in the future is referenced and no calendar instance is found.

Where referenced

You can associate a calendar with operators (in the Operator ID data instances), organizations, and work queues.

References to calendars identify only the first key part. The system uses a context-determined date as the (starting) second key part.
