A cron expression is a string of five fields that defines a schedule for running automated tasks. The five fields represent minute, hour, day of month, month, and day of week. Cron is used in Unix/Linux systems, CI/CD pipelines, cloud schedulers (AWS CloudWatch, Google Cloud Scheduler), and job queues. Our free generator lets you build cron expressions visually or parse existing ones to see what they mean in plain English.
