What is a Cron Expression?
A cron expression is a string consisting of five fields that represent a schedule. Each field specifies when a job should run: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-6, where 0 is Sunday).
Cron Expression Syntax
- Asterisk (*): Matches all values (every minute, hour, etc.)
- Comma (,): Separates multiple values (1,3,5)
- Hyphen (-): Defines a range (1-5)
- Slash (/): Specifies step values (*/5 = every 5 units)
Common Use Cases
- Scheduling database backups
- Running maintenance scripts
- Sending automated reports
- Cleaning up temporary files
- Triggering CI/CD pipelines
- Synchronizing data between systems
