How to use the gantt chart builder

  3. Read the timelineThe chart scales automatically to fit every task, with a marker for today.

Keeping a Gantt chart simple

A Gantt chart does not need complex dependency logic to be useful. Just knowing when each task starts relative to the project kickoff, and how long it runs, is usually enough to spot scheduling conflicts, gaps, or an unrealistic pile-up of work in one week. This tool keeps the model deliberately simple, so you can sketch out a rough project timeline in a couple of minutes rather than fighting with a heavier project management tool.

Watch for pile-ups

If several bars stack up in the same window, that is often a sign the schedule is too tight.

Update as you go

Since start offsets are relative to the project start date, shifting the whole plan is as easy as changing one date field.

Gantt Chart Builder FAQ

How do I set when a task starts?

Enter its start as the number of days after the project start date, not a calendar date. The chart converts that into an actual date for you automatically.

What does the red vertical line mean?

It marks today's date on the timeline, if today falls within the current project span.

Can tasks overlap?

Yes, overlapping tasks are common in real projects and the chart will show their bars overlapping on the timeline.

Can I export the schedule?

Yes, use Download as CSV to get a spreadsheet-ready file with each task's name, start date, duration and end date.
