Markwhen is a markdown-like journal language: you write markdown-ish text and it is converted into JSON, which can then be rendered into a timeline, calendar, or other view. It supports groups, tags, checklists, links, custom date formats, timezones, recurrences, and frontmatter properties. The project includes a parser, a CLI, a VS Code extension, an Obsidian plugin, and view/timeline/calendar rendering libraries.
