Cron Syntax Explained
Cron syntax is compact but logical. This breakdown covers every symbol you will encounter.
Fields and ranges
Minute is 0–59, hour 0–23, day-of-month 1–31, month 1–12, and day-of-week 0–7 (where both 0 and 7 mean Sunday). An asterisk means every valid value for that field.
Lists, ranges and steps
A comma makes a list (1,15,30), a hyphen makes a range (1-5), and a slash makes a step (*/10). These can combine, so "0-30/5" means every five minutes in the first half of the hour.
Frequently asked questions
Can I use this for production work?
Yes, for inspection, formatting and quick generation. Still review the output before committing it to production code or configuration.
