Cron schedules run commands at specified times on Unix-like systems. Each schedule line lives in a file called crontab.

The Crontab Generator lets you compose correct schedule expressions without memorising syntax. You pick intervals or enter patterns.

You then copy the generated line into your server’s crontab to automate backups, reports, or housekeeping tasks.

Answers to common questions.

Can I schedule multiple commands?

No. Create one line per command for clarity.

Does the asterisk mean “every”?

Yes. It tells cron to match all possible values in that field.

Are ranges inclusive?

Ranges include both start and end numbers.

What timezone does cron use?

Cron follows the server’s local timezone unless configured otherwise.

How do I edit existing jobs?

Run crontab -e in your shell; insert or modify lines as needed.
