Cron Expression Format

┌───────────── minute (0–59)
│ ┌───────────── hour (0–23)
│ │ ┌───────────── day of month (1–31)
│ │ │ ┌───────────── month (1–12)
│ │ │ │ ┌───────────── day of week (0–6, Sunday=0)

* * * * *

Special Characters

• * — matches any value (e.g., * in minute = every minute)
• , — list separator (e.g., 1,15 = at minutes 1 and 15)
• - — range (e.g., 9-17 = hours 9 through 17)
• / — step (e.g., */10 = every 10 units)
