> Index of every page on this site: [llms.txt](https://wagenfuehrer.com/llms.txt). Any page is available as markdown by adding `.md` to its address.

Practise the Doomsday rule: a random date, seven buttons, and the century, year, month and day working shown after every answer.

It's an interactive tool, so it needs a browser with JavaScript.

The method itself is explained at https://wagenfuehrer.com/doomsday.
