What Is a Cron Expression?
Cron is a time-based job scheduler in Unix systems. A cron expression defines when a task should run using 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-6, Sunday=0). Special characters include * (any), , (list), - (range), and / (step).
