# A history timeline maker for teachers and students

Put an era, a revolution or all of deep time on one axis, and zoom from billions of years to a single afternoon. The timeline below runs from the Big Bang to the Sun's last light. Read it in a lesson, embed it in a course page, or print it as a poster.

## From deep time to a single second

One continuous axis holds the age of the universe and a launch countdown alike. Drag, scroll or pinch to move; crowded items gather into clusters until you zoom in on them.

- Dates in deep time read as ages, such as 66 Ma or 4.5 Ga AP, the way the sources give them.
- Find any item by its title with / or ⌘K.
- On a phone the axis stands upright, so students scroll through time with a thumb.

## Read an era against the world

Lay up to three timelines beneath the one you are reading: a revolution against the century around it, a reign against its neighbours.

- Pick from your own, your team's, shared and public timelines.
- Drag or zoom once and every strip moves with it.
- Free on every plan, and a student who opens the link sees the same view without signing in.

## On the course page, not behind a link

Show a timeline inside a blog post or a course page, and let students explore it right where they are. Free on every plan.

- Paste a URL, or a code snippet for pages that take HTML.
- A private timeline embeds through a share link.
- Pick its language, and a light or dark theme, to suit the page.

## A picture of the view, or a poster

Frame any part of a timeline and save it as an image or a PDF page for a slide or a handout, or print the whole timeline as a poster for the classroom wall.

- Pick a shape, from 16:9 to A4, and keep zooming underneath the frame.
- PNG or PDF, light or dark, with a caption if you want one.
- A poster puts the whole timeline on one sheet, and shortens long empty stretches so the eras that matter stay readable.

**Pro & Team** Posters come with Pro and Team, and a picture of the view then has no small Timescrolly mark.

## Tags for topics, collections for courses

Tag the items on a timeline, and the timelines themselves. Group whole timelines in a collection, such as the unit you are teaching.

- Your tags follow you from one timeline to the next.
- Filter by tag and share a link to exactly that view.
- Keep a collection to yourself, or share it with your team.

## Start from the text you already have

Give the timeline assistant a PDF, a spreadsheet or your own lecture notes, and it drafts the events and periods it finds. Nothing is added until you have reviewed it.

- Bring PDFs, Word and Excel files, CSV and text files, photos and scans, or text you paste in.
- Start a new timeline from a document, with a description and category suggested for you, or add to one you already have.
- Each draft shows the quote it rests on, and is flagged when its date is uncertain or the timeline already seems to have it.

**Pro & Team** A much larger monthly allowance of credits. Free comes with a smaller one.

## Coming from slides or a document?

A timeline drawn on a slide is fixed the day you make it. Here the same timeline zooms, and students can go from the century to the week.

A table of dates in a document can't show that two eras overlapped. On one axis they do, and a context timeline lays one beneath the other.

A spreadsheet lists the events but doesn't teach their order. Import it, and the table becomes something a class can scroll through.
