Exclusions in Overlay Calendars

Overlay calendars define exclusions to the normal working hours defined in the base calendar. While some exclusions are one-off, many will repeat over a defined period of time.

For example, you can define such exclusions as:

  • Every Friday from 14:00 to 18:00
  • The first Monday of the month, for the next six months

These exclusions are defined using a recurrence rule that sets out how the start datetime of each occurrence of the exclusion is calculated. The rule is given in the standard notation set out in the industry standard RFC-5545.
