What is Cron Expression?
A cron expression is a compact string of fields that specifies when a recurring job should run, typically covering minute, hour, day of month, month, and day of week. It is used by schedulers on Unix-like systems and in many apps to automate backups, reports, and cleanup tasks. Each field accepts values, ranges, lists, and step patterns to describe schedules from once a year to every minute.
