History Timeline Maker
Build visual history timelines from pipe-separated events. Parse year, year-month, full date and BC/AD dates, sort chronologically or reverse, group by category, color-code events (rainbow / mono / category schemes), render as ASCII vertical timeline, HTML (printable), Markdown, or CSV. Compute spans between events, search/filter, summary stats (date range, by-category counts), era calculator (1945 → 20th century), event importance markers (1–5 stars), 4 timeline presets (WWII, American Revolution, Ancient Egypt, Renaissance), history (localStorage), and shareable URL. 100% client-side — no network.
