How do I make a project timeline with milestones?

Open AnyTool’s Project Timeline Maker and you get a starter roadmap of milestones. Add a milestone, then set its date, title, a one-line description, an optional phase/track and a colour — the milestones auto-sort by date and render as a clean timeline. Switch between a horizontal line (markers along an axis with labels alternating above and below) and a vertical stacked line, and space them by their real dates or evenly in sequence. Status (done / current / upcoming) is derived from today automatically, with a red today line on the date axis, or you can set each one by hand. The whole timeline is saved automatically in this browser’s localStorage; export it as a PNG image or a JSON file (and import the JSON back), or print it — everything runs 100% in your browser, nothing is uploaded.

  • Each milestone: date, title, one-line description, optional phase/track and a colour; auto-sorted by date
  • Layouts: horizontal (alternating labels) or vertical (stacked), spaced by real dates or evenly in sequence
  • Status done / current / upcoming derived from today, plus a red today marker — or set status by hand
  • Export as PNG and the whole timeline as JSON; import JSON to restore; print a clean handout
  • Saved only in your browser; a roadmap overview, not a task scheduler — use Gantt Chart for durations & dependencies

What is

Project timeline

A project timeline is a linear, chronological map of a project’s key milestones and phases from start to finish, used to communicate the plan at a glance in a deck or one-pager. Each milestone is a dated event — a kickoff, release, approval or launch — placed in order along a line, often with a short label and a status. AnyTool’s Project Timeline Maker is a 100% client-side roadmap builder: it sorts milestones by date and renders them as a horizontal or vertical timeline (spaced by real dates or evenly), derives a done/current/upcoming status from today with a today marker, and exports PNG and JSON — saved to your browser’s localStorage. It is distinct from a Gantt chart, which schedules tasks with durations and dependencies.

Frequently Asked Questions

It is saved only in your browser’s localStorage and never uploaded — there is no account, server or tracking, so it stays completely private to this browser.

AnyTool’s Project Timeline Maker is 100% client-side. The whole timeline — every milestone, date, phase, description, colour and status — is stored in your browser’s localStorage and is never sent to any server. There is no sign-up, no login and no analytics, and the tool keeps working offline once the page is cached. Because the data lives only in your browser, clearing your browsing data or switching to a different browser or device removes it, so use Export to download a JSON backup (or a PNG snapshot) you can keep and re-import any time.

A timeline is a high-level roadmap of dated milestones for an at-a-glance overview; a Gantt chart schedules tasks with durations, progress and dependencies — use the separate Gantt Chart tool for that.

This Project Timeline Maker is a presentation roadmap: a clean chronological line of milestones (kickoffs, releases, approvals, launches) that communicates the plan at a glance for a deck or one-pager. It deliberately does not model task durations, percent-complete or dependencies. If you need to schedule the day-to-day work — task bars with start and end dates, progress fills and finish-to-start dependency arrows — use AnyTool’s separate Gantt Chart tool instead. Many teams use both: a timeline to set and share the direction, and a Gantt chart to manage delivery.

Yes — toggle between a horizontal line with labels alternating above and below and a vertical stacked line, and choose spacing by real dates or evenly in sequence.

The timeline has an orientation toggle and a spacing toggle. Horizontal draws the milestones as dots along a single axis with their cards alternating above and below the line so labels do not overlap, and the strip scrolls sideways when it is wide; it switches to a comfortable stacked layout on small screens. Vertical draws a centre line with cards alternating left and right. The spacing toggle is either by-date — positions reflect the real gaps between dates, so a long pause looks long — or even, which spaces milestones equally in sequence for a tidy roadmap regardless of the date gaps. On the date axis a red dashed today line marks the current date when it falls inside the span.

Use Export to download the timeline as a PNG image or the whole timeline as a JSON file, Import to load a JSON back on any browser, or Print for a clean handout.

Because the timeline is a personal, single-device tool with no cloud sync, exporting is how you back it up or move it. PNG export renders the timeline node to an image with html2canvas (loaded only when you click) so you can drop it into a slide, doc or email. JSON export downloads the entire timeline — title, milestones, dates, phases, colours and statuses — as a formatted file; Import reads such a file and replaces the current timeline, validating and migrating the data so an older or hand-edited file still loads safely. Print uses your browser’s print dialog for a clean one-page handout or PDF. Keep an exported JSON backup so a cleared cache or a switched browser never loses your work.

Detailed Explanation

Methodology

The Timeline Model and Layout Maths

AnyTool’s Project Timeline Maker keeps a single timeline object as its source of truth: a timeline has a title and an array of milestones, and each milestone carries a title, an ISO date, an optional one-line description, an optional phase/track label, a colour and a status (done / current / upcoming) with a statusMode flag of auto or manual. For rendering the milestones are sorted by date. Two spacing modes convert dates to positions along a 0–1 fraction: in by-date mode the fraction is (date − minDate) ÷ (maxDate − minDate) so the gaps between markers reflect the real time between them; in even mode the fraction is index ÷ (count − 1) so milestones are spaced equally in sequence regardless of date gaps. Two orientations render those fractions: horizontal places dots along a single axis with their cards alternating above and below the line to avoid overlap (the strip scrolls sideways when wide), and vertical draws a centre line with cards alternating left and right. On the date axis a red dashed today line is drawn at the today fraction when the current date falls inside the span. This is a presentation roadmap, not a Gantt-style scheduler: there are no task durations, percent-complete bars or dependency arrows.

  • Timeline → title + milestones; each milestone has date, title, description, phase, colour, status and statusMode
  • Milestones are sorted by date for rendering
  • By-date fraction = (date − minDate) ÷ (maxDate − minDate); even fraction = index ÷ (count − 1)
  • Horizontal: dots on an axis, cards alternate above/below; vertical: centre line, cards alternate left/right
  • A red dashed today line marks now on the date axis when today is inside the span
How It Works

Status, Phases and the Today Marker

Each milestone has a status of done, current or upcoming. In auto mode the status is derived from the device clock: every milestone whose date is before today is done, the first milestone on or after today is current, and the rest are upcoming — so the timeline keeps itself honest as time passes. Switching a milestone to manual pins its status to a chosen value. Statuses drive a coloured ring around the marker dot and a small badge on the card, and a stats strip summarises the counts of done, current and upcoming milestones. An optional phase/track label groups milestones (for example Discovery, Build, Launch); the distinct phases are collected and shown as a small legend beneath the timeline, and the editor offers existing phase names as suggestions. The colour palette gives each marker a brand colour for the dot, card border and date label, so phases and themes read clearly at a glance in a deck or one-pager.

  • Status done / current / upcoming, auto-derived from today or set manually per milestone
  • Auto: past = done, the first one on/after today = current, the rest = upcoming
  • A red dashed today marker appears on the date axis when today is within the span
  • Optional phase/track labels group milestones and render as a legend; the editor suggests existing phases
  • A stats strip reports milestone count, phase count, the date span and done/current/upcoming counts

Local Storage, Export and Honest Limits

Everything runs locally in the browser with no account, server or tracking. The whole timeline is serialised to localStorage on every change, so it survives a refresh, and the tool works offline once the page is cached — nothing is ever uploaded. Export renders the timeline node to a PNG with html2canvas (lazy-loaded only when you click) and also exports the whole timeline as formatted JSON; Import validates and migrates such a JSON file — normalising dates, falling back to safe colours and statuses, and dropping anything malformed — before replacing the timeline, so older or hand-edited files load safely. Print uses the browser’s own dialog for a clean one-page handout or PDF. Honestly, this is a presentation timeline / roadmap, not a task scheduler: it has no durations, percent-complete or dependencies — for those use AnyTool’s separate Gantt Chart tool. It is also a personal, single-device tool with no cloud sync, shared link, comments or collaborator assignment. Because the data lives only in your browser, keeping an exported JSON backup is recommended, and resetting to the starter example asks for confirmation first.
