Zovo Timeline

Turn dated events into a clean timeline you can print or share.

Zovo Timeline turns a list of dated events into a timeline chart. Events are placed to scale by their day count, or at even gaps if you prefer. Labels are staggered into rows so they do not overlap. Spans such as wars or reigns are drawn as bars, and eras as shaded bands. BC dates are supported, and the chart notes that 1 BC is followed by AD 1. You get an SVG image, a PDF for Letter or A4 paper, and a CSV of the events with their positions.
