Timeline Source, for dates that refuse to sit still

Field notes

The tool models chronology as a connected canvas: users can drag and zoom through events, open notes, represent uncertain dates as ranges, and attach one event to another event’s milestone. The homepage presents a worked example focused on the ancient Near East and Mediterranean, alongside browsing categories from Greece and Rome through the modern era. It also says public timelines can be compared or imported with credit, while private work remains private until publication.
