What is a crontab generator?

A UI that writes the five Unix cron fields for you and translates the result into English plus upcoming run times.

How do I run a job every 5 minutes?

Use */5 * * * *. That is the default preset on this page.

Unix accepts both. This parser maps 7 to 0.

What if both day-of-month and day-of-week are set?

Unix cron ORs them. 0 0 1 * 1 runs on the first of the month or on Mondays.

Does this install a crontab?

No. It only builds the expression. Paste it into crontab -e, a Kubernetes CronJob, or systemd.
