What is a Cron Expression?

A cron expression is a string of 5 fields separated by spaces that defines a schedule for automated tasks. Used in Linux crontab, GitHub Actions, Vercel, AWS CloudWatch and most CI/CD systems. The five fields represent minute (0-59), hour (0-23), day of month (1-31), month (1-12) and day of week (0-6).
