Hi Nivedita, 
In Gantt, we can customize the dates for parent task and the dates are independent of its child tasks. It can be achieving by adding the Boolean property for parent tasks in the data source to consider as   manual scheduling mode and use the API’s “taskSchedulingMode” as “custom” and “taskSchedulingModeMapping” as “Boolean property name” to enable this support. 
Please refer following code snippet, 
var scheduleModeData = [ 
                 "TaskID": 1, 
                 "TaskName": "Parent Task 1", 
                 "StartDate": new Date("02/23/2014"), 
                 "EndDate": new Date("02/27/2014"), 
                 "Progress": "40", 
                 "isManual" : true, 
                 "Children": [ 
taskSchedulingModeMapping: "isManual", 
taskSchedulingMode: ej.Gantt.TaskSchedulingMode.Custom, 
We have also prepared sample for this and to know more details about task scheduling mode, please refer following links.
