About Timeline

Turn a start date, duration, and phase count into an evenly spaced milestone timeline.

Enter the project name, start date, total weeks, and how many phases it has. The generator spaces milestones evenly — kickoff first, delivery last, checkpoints between — each stamped with a calendar date.

Even spacing is a starting skeleton: shift dates for dependencies, reviews, and holidays before committing. Everything runs in your browser.

Where it is used

Client proposals, sprint planning kickoffs, event countdown schedules, and course module planning.

How to use the Timeline

  1. Project Name — enter the value (e.g. Website redesign).
  2. Start Date — enter the value.
  3. Duration (Weeks) — enter the value (e.g. 8).
  4. Number of Phases (2–10) — enter the value (e.g. 4).
  5. Calculate — press the Calculate button to see the result instantly above.

Formula

Milestone i lands at start + round(totalDays × i / phases).

Examples

Example

projectName:Website redesign
startDate:2026-10-01
durationWeeks:8
phases:4
Result: Kickoff Oct 1 → checkpoints → delivery Nov 26 (5 milestones)

Frequently Asked Questions

Should phases really be evenly spaced?
Rarely in practice — discovery and QA usually need more room than build. Use this skeleton, then stretch phases by effort.
How do I handle dependencies?
List them beside each milestone after generating. A timeline shows when; a dependency list shows what blocks what.
Can I export this to a Gantt tool?
Copy the dated list into any spreadsheet or Gantt app — the ISO dates paste cleanly into date columns.
