About Gantt Chart Maker

A Gantt chart lays the tasks of a project out against a calendar, so you can see what happens when, what overlaps and when the whole thing finishes. Each task is a bar. The length shows how long it takes, and the position shows when. They are most useful when some tasks cannot start until others finish, because a delay to one early task can push back everything after it.

Add your tasks with a name and a number of days. Give a task a start date, or say that it starts after another task and it will begin the day after that one finishes. Tasks with neither begin on the project start date. The chart redraws as you type with a bar for each task, a stripe showing how much is done, week markings and a line for today. A summary shows the first day, the last day, the total length and the longest chain of linked tasks, which is the chain that sets the finish date. Choose working days only to skip weekends, and download the picture as a PNG.

Frequently asked questions

How do I make one task follow another?

Enter the number of the earlier task in the Starts after box. The task begins the day after that one ends, or the next working day if you are counting working days.

What if I give a start date and a link?

The later of the two is used, so a task never starts before the task it follows, but it can be held back to a date you choose.

What is the longest chain?

The linked tasks that set the finish date. These are outlined on the chart. Delay any of them and the project finishes later.

How are working days counted?

With the option ticked, weekends are skipped and a task that would start on a Saturday or Sunday starts on Monday. Bank holidays are not skipped.

Can I save the chart?

Download it as a PNG image. The page does not keep your tasks when you leave, so write down the task list if you want to come back to it.
