About cron expressions
A cron expression is a string of five fields separated by spaces that defines a recurring schedule: minute hour day month weekday. Each field accepts a number, a wildcard (*), a range (1-5), a step (*/15), or a list (1,3,5).
Special strings like @daily, @weekly, and @hourly are shorthand aliases supported by most schedulers including crontab, GitHub Actions, and Kubernetes CronJobs.
