About Cron Expressions

Cron expressions are used to schedule tasks to run automatically at specific times or intervals. They consist of 5 fields: minute, hour, day of month, month, and day of week.

Special characters:

* (asterisk) - Any value (e.g., * in hour means every hour)
, (comma) - List of values (e.g., 1,3,5)
- (dash) - Range of values (e.g., 1-5)
/ (slash) - Step values (e.g., */5 means every 5 units)

Use cases: Task scheduling, automated backups, report generation, data synchronization, system maintenance
