Frequently Asked Questions
Is my data sent to a server when using the Crontab Generator?
No. The Crontab Generator is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
What is crontab syntax?
A crontab syntax is a time-based job scheduler expression containing 5 or 6 fields representing Minute, Hour, Day of Month, Month, Day of Week, and optional Year. Asterisks denote 'every' unit.
How do I schedule a job for every 5 minutes?
You can write the expression `*/5 * * * *` which instructs the scheduler to fire at every interval that is divisible by 5.
What is the difference between standard and non-standard cron?
Standard cron operates with minute resolution. Some server platforms support non-standard extensions including a sixth field for second resolution or special tags like `@hourly`.
Does the Crontab Generator store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the Crontab Generator compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the Crontab Generator work offline?
Yes. Once loaded, all code and assets required to run the Crontab Generator reside in your browser cache, enabling offline use without an active network connection.
