Cron Expression Generator FAQ

What do the five cron fields mean?

Minute (0–59), hour (0–23), day of month (1–31), month (1–12) and day of week (0–6, Sunday is 0 or 7). * means every value, */15 every 15th, 1-5 a range and 1,15 a list.

What happens when both day fields are set?

In standard cron the job runs when either matches: 0 0 1 * 5 runs on the 1st and on every Friday. Quartz and EventBridge require ? in one of them.

Which formats are supported?

Standard 5-field cron, 6 fields with seconds (Spring, node-cron), Quartz (with ? L W and #), AWS EventBridge cron(…) and @hourly, @daily, @weekly, @monthly and @yearly.

Which time zone does cron use?

The server’s, unless your scheduler sets one (Kubernetes CronJob timeZone, EventBridge Scheduler). Pick that zone here to see the real run times.

Is it free?

Yes, free with no sign-up, and it runs in your browser.
