Project Timeline Generator
Create visual project timelines with milestones and dates
What is Project Timeline Generator?
The Project Timeline Generator is a free tool that turns a list of tasks and milestones into a clear, visual schedule. You add each item with a name, a start date or a duration in days, an optional phase, and a dependency on another task, and the tool computes the end dates and arranges everything into a Gantt-style timeline that shows how your project lines up over time. Tasks become coloured bars with a progress fill, milestones become diamonds, and items are grouped by phase. A working-days option skips weekends, and a summary panel reports the project start, end, total duration, and overall completion. Instead of scattered dates in a spreadsheet, you get an at-a-glance picture of what happens when. It runs entirely in your browser, needs no signup, and keeps your plan private.
How to use Project Timeline Generator?
Building a visual project schedule takes only a few minutes:
- 1 Add tasks and milestones, giving each a clear name. For a task, set a start date or a duration in days; for a milestone, set the date it must be reached. Group related items by typing a phase name so the chart organises them into sections.
- 2 Link dependencies by choosing which task an item starts after. The tool automatically schedules the dependent task to begin the day its predecessor finishes, then recomputes the end date and the whole timeline for you.
- 3 Set scheduling options: turn on working-days mode to skip weekends when calculating durations and end dates, set a project start date for items without a fixed date, and toggle weekend shading on the chart.
- 4 Read the summary and Gantt chart, then track progress by entering each task's percentage complete. Review weekly and adjust dates or durations as the project evolves — the timeline and totals redraw instantly.
Why use this tool?
A written list of dates is hard to reason about, but a visual timeline makes the shape of a project obvious in seconds. With auto-computed end dates and dependencies, you set a start and a duration once and the tool keeps every downstream date correct, so a single change ripples through the schedule without manual recalculation. Phases group related work, milestones mark the dates that matter, and progress bars show how far each task has come — giving stakeholders an instant read on health and pace. The working-days option produces realistic estimates by excluding weekends, and the summary turns the plan into headline numbers: total duration and overall completion. Because the generator works locally in your browser, your roadmap and dates never leave your machine, making it safe for confidential plans while remaining fast and free to use.
Examples
Tasks for research, design, development, and beta are chained by dependency, each with a duration in working days, ending in a launch milestone. The tool computes every date and renders the full road to release.
Each task is given a percentage complete, and the summary reports an overall progress figure while progress fills appear inside every bar — turning the timeline into a live status dashboard.
A ten-day task starting on a Thursday would normally finish across two weekends. With working-days mode on, the tool skips Saturdays and Sundays and pushes the end date to the correct business day.
Frequently Asked Questions
What is a Gantt-style timeline?
It is a horizontal bar chart where each task or phase is drawn against a calendar, so its start, end, and duration are visible. Milestones appear as diamonds. It makes the sequence and overlap of project work easy to understand at a glance.
How do dependencies work?
For any task you can choose another task it depends on. The dependent task is automatically scheduled to start the day after its predecessor finishes, and its end date is recomputed from its duration. Circular dependencies are detected and flagged.
What does the working-days option do?
When enabled, durations and end dates count only Monday to Friday, skipping weekends. A task starting on Friday with a duration of three days will therefore end the following Tuesday rather than the Sunday.
How is percentage complete used?
Each task can carry a percentage complete, shown as a fill inside its bar. The summary combines these — weighted by duration — into a single overall progress figure for the whole project.
How is this different from a critical path tool?
This timeline focuses on visual scheduling: start dates, durations, phases, milestones, and progress. A critical path calculator analyses dependencies to find which chain of tasks controls the deadline. The two complement each other.
Is my project plan stored anywhere?
No. The timeline is generated entirely in your browser, so your tasks, dates, and durations are never uploaded to or saved on a server, keeping confidential plans private.
