Cron expression
Build and explain a cron
In plain words
Next runs
This tool builds and explains a cron expression: pick minutes, hours, days and months, read the schedule in plain words and see the next run dates. Great for scheduling a backup, a script or a recurring job without getting the syntax wrong.
Everything is computed in your browser: no expression sent, no tracking and no ads.
