It's about time.

Markwhen is the offline-first, plain text calendar and planning app you've been waiting for.

Web app

Open in new tab

Start with when.

Markwhen is a file format (and editor) that brings when into the limelight. Usually time is just metadata on something else.

It's time we bring time to the forefront.

What an *incredible* little tool to generate timelines, e.g. for project planning or life timeline! You write markdown-ish text and it gets converted into a nice looking cascading timeline.

i am an absolute sucker for every single "markdown-ish DSL for pernsickety layouts" tool out there, and this is no exceptionhttps://t.co/MUPBwbHgAo pic.twitter.com/Z9sKONIrcD

This is fun: it’s Markdown (that is: a text file that makes sense and is easy to work with on its own) but it generates cascading timelines (project diagrams, timeline charts). https://t.co/lH6YxH8NRw
