When to use it

Kick-off meetings, the progress recap in weekly or monthly reports, and steering committee slides. section groups the points in time into phases, one colour per phase, so each milestone shows which phase it belongs to.

Making it yours

  • Points in time can be weeks, months or dates; change the text before the colon.
  • Phase names follow section; delete the section lines if you do not need phases.
  • Each point can hold any number of events separated by colons.
  • For day-level scheduling use a Gantt chart instead; see the "Project schedule Gantt chart" template.

Send the prompt below to ChatGPT or Claude, then paste the whole reply into the editor; the code inside is detected automatically.

Draw a project milestones timeline in Mermaid timeline syntax titled Project milestones, with sections Kick-off, Design, Build and Launch; points in time are weeks (Week 1, Week 2-3, and so on), each with one or two milestones (project approved, prototype review, technical design review, feature freeze, acceptance testing passed, go-live, retrospective), separated by colons within a point in time. Output only the mermaid code block.

FAQ

Timeline or Gantt chart?

A timeline only records what happened when and suits reports and recaps; a Gantt chart has durations and dependencies and suits planning and tracking. Put the timeline on the slide and the Gantt chart in the appendix.

Does indentation inside a section matter?

No, indentation is for readability. Every point in time between one section and the next belongs to that section.

Can I mark the current position?

Mermaid timelines have no "now" marker; add a check mark or "in progress" to the event text instead.
