    Cron expressions control scheduled jobs on servers, CI pipelines and tools like cron and Kubernetes, but their five fields (minute, hour, day-of-month, month, day-of-week) are easy to misread. This parser explains the schedule in words and lists the next run times so you can catch mistakes before they hit production. It all runs in your browser.
