AIXM supports the encoding of schedules that contain both repetitive time periods and occasional occurrences. The coding guidelines for schedules/timetables can be found in: AIXM Coding Overview - Common Coding Rules - Schedule [TSH]. These general coding guidelines for schedules are also applicable to Digital NOTAM Events. However, based on the limitations specified in the OPADD document, only a subset of schedules is allowed for temporary events published by NOTAM. The limitations are described further down in this section.

The information items that may occur in the definition of schedules are identified in the diagrams described in the Common Coding Rules - Schedule [TSH], section Common coding patterns. For use of "daily", "on date" and "date ranges" templates please refer to Common coding patterns - "Daily" schedules diagram. For use of "on weekday" and "from weekday...to weekday" please refer to Common coding patterns - "Weekday" schedules diagram.
