Turn a cron expression into plain English and see the next 5 fire times.
⏰ Supports standard 5-field cron: * (any), , lists, - ranges, / steps, and named months/days (JAN–DEC, SUN–SAT). Day-of-month and day-of-week follow Vixie cron OR-logic: when both are restricted, the job runs if either matches.
A cron expression is a compact string that describes a repeating schedule — the same format used by Linux crontab, GitHub Actions, Kubernetes CronJobs, and AWS EventBridge. This parser turns that string into plain English and shows the next five times it will fire, so you can confirm a schedule before deploying it.
Left to right, the fields are minute (0–59), hour (0–23), day of month (1–31), month (1–12 or JAN–DEC), and day of week (0–6, where 0 = Sunday, or SUN–SAT). Each field accepts * (any value), a comma list (1,15), a range (9-17), or a step (*/15 for every 15 minutes). A classic example: 0 9 * * 1-5 means 09:00 on weekdays.
When both the day-of-month and day-of-week fields are restricted (neither is *), cron fires if either matches — this is the Vixie cron standard. So 0 0 1 * 1 runs at midnight on the 1st of the month or on any Monday. If one of those fields is *, only the other is considered. This is the most common source of cron confusion, so always verify with the next-runs preview.
While the five core fields are standard, macros (@daily, @reboot), seconds, and years are notuniversal. GitHub Actions, Kubernetes, and AWS EventBridge each add their own fields or syntax. This parser covers the standard five-field format used by Linux crontab; confirm any extra fields against your specific platform's docs.
The Cron Expression Parser handles cron parserdirectly in your browser. Paste or type your input, and the tool processes it instantly — no upload, no signup, no waiting. It's built for the moments when you need a quick transformation and don't want to leave your workflow.
Because the tool runs client-side, it's fast and private. Your text never touches a server, which makes it safe for sensitive content. The interface is keyboard-friendly and works on any device with a modern browser.
Common uses: people reach for this tool when they need to use a cron expression to english, next cron run time calculator, 5 field cron schedule explainer, or cron job trigger time preview.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
