Enter the shell command to run.
Copy the crontab line into crontab -e on your server.

FAQ

What do the five cron fields mean?

Minute (0–59), hour (0–23), day (1–31), month (1–12), weekday (0–7, 0 and 7 are Sunday). * means every value in that field.

How do I run a job every day at midnight?

Set minute 0, hour 0, and * for the rest, then add your script path—or use the daily midnight preset.

How is crontab different from systemd timers?

Crontab is the classic Unix scheduler with wide support. systemd timers integrate tightly with services on modern Linux.

Is schedule generation local?

Yes. Lines are built locally in your browser.
