Cron explainer & builder

Both directions: type a cron expression to get a human description and the next run times — or compose the expression from its five fields below.

Everything runs in your browser — your input is never sent anywhere. Only an anonymous conversion counter is recorded.

Shortcuts like @hourly, @daily, @weekly are understood too.
