DayPilot.Gantt.tasks.businessEnd

The tasks.businessEnd() returns the adjusted end date of a task:

1. Starts with the task’s current start date and its business-only duration.

2. Scans the resulting date range for any cells marked non-business (weekends, holidays, etc.).

3. Shifts the end date forward by the length of every non-business interval it encounters, so that the total business duration is preserved.

4. Returns the final end date that now fully covers the original business duration plus any skipped non-business time.

The non-business cells can be defined using the onBeforeCellRender event handler.

Available since 2025.3.6564.
