Understanding Cron Expressions
A cron expression uses five fields: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–6, Sunday=0). Use * for any value, */n for steps, ranges like 1-5, and lists like 1,15,30.
Frequently Asked Questions
Does this support 6-field cron with seconds?
This tool parses standard 5-field cron (minute through weekday). If you paste a 6-field expression, the seconds field is ignored and the remaining five fields are used.
Which timezone are run times shown in?
Run times use your browser's local timezone and locale formatting. Server cron jobs typically run in the server's timezone — adjust accordingly.
