Greetings from Syncfusion support.
In Gantt, we are validating the dates based on various properties such as DayWorkingTime, WorkWeek, IncludeWeekend, Holidays and PredecessorMapping. To show the date as given in the data source, we need to make 24 hours as working day by specifying the range as 0 to 24 and also we need to enable IncludeWeekend property to make the weekends also as working days. When predecessor is mapped, dates are validated based on the predecessor values.To disable the predecessor validation, we need to disable the property EnablePredecessorValidation. When duration field is mapped, end dates are calculated based on the start date and duration. To show the end date as same as the date given in the data source we should not map duration field. Please refer the below code snippet for this.
Please get back to us if you require further assistance on this.

As the parent task is dependent of child tasks, the start date and end date of parent task will be calculated based on its child task’s start date and end date. This is the current behavior of Gantt. We cannot change its date in work around also.
Please get back to us if you need more information on this.
