Tools to handle the realities of history
Everything you need to make sense of the history we know, with the flexibility to identify the uncertainties.
Years to minutes
Date an event as exactly as you know it, and no more exactly than that.
Notes
Attach references, sources, and other information to individual events.
Make sense of uncertainty
If you’re unsure about a date, make your best estimate, and specify the uncertainty.
Link events
Tie events together if their relative dating is known.
Anchor events
If a date is known with certainty, anchor it to that moment, and it won’t move.
Import and overlay
Overlay other timelines on yours, and import them to build on the work of others.
Share with a link
Publish a timeline and send the link. Anyone can open it — no account needed to read.
Snapshot
Instantly grab a snapshot of the current timeline, and either copy it to the clipboard or download it as a PNG.
Start from someone else’s work
Read any public timeline, lay it over your own, or import it — its author is always credited.
