Understanding the 5 Standard Cron Fields
Cron is a time-based job scheduler in Unix-like operating systems. A standard cron schedule expression consists of 5 fields separated by spaces: `[minute] [hour] [day-of-month] [month] [day-of-week]`.
Special characters extend scheduling flexibility: `*` (any value), `,` (value list separator), `-` (range of values), and `/` (step values, e.g. `*/15` for every 15 minutes).
