Frequently asked questions
How many fields does a cron expression have?
Standard cron has five: minute, hour, day of month, month and day of week. Some schedulers add a leading seconds field, which this tool also understands.
Which time zone are the next runs in?
Your browser's local time zone by default. Switch to UTC to see the runs the way most servers and CI systems evaluate them.
Are my files uploaded anywhere?
No. Cron Expression Explainer runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Cron Expression Explainer really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
Does it work offline?
Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
