end_date is not i want

why the end_date is 15 not 14

Hello, Gantt stores end dates in a 'not inclusive' format. Meaning that the end date of the task in your example will be stored as 2022-04-15 00:00 – midnight after April 14th. By default, these dates are displayed as is, so the user may get the impression that the task takes one extra day. You can redefine the task_end_date template to change the format of the end dates of tasks in the Gantt (i.e. to include the end date in the duration of the tasks): https://docs.dhtmlx.com/gantt/api__gantt_task_end_date_template.html For more details on formatting end dates, see the Task end date display & Inclusive end dates article: https://docs.dhtmlx.com/gantt/desktop__loading.html#taskenddatedisplayampinclusiveenddates Please check the example of how it might be implemented: https://snippet.dhtmlx.com/5i3349k4 If you meant something different, please clarify your question.

Hello, If the parent task type is a project, you can change the task type of the project to task. There is an article about it: https://docs.dhtmlx.com/gantt/desktop__task_types.html If the parent task type is task, you need to check that start_date, end_date, duration parameters are set correctly, in case if there are no parameters, the task can behave like a project. Please check the example in the following snippet: https://snippet.dhtmlx.com/p4yn7zgv ; If it doesn't help you, please reproduce your issue in the snippet, click the "Save" button and send the link to us.
