Frequently Asked Questions

What cron format is this?
Standard 5-field Unix crontab: minute, hour, day-of-month, month, day-of-week. Step (*/15), range (1-5), and list (1,3,5) syntax are supported.
Does it run my cron job?
No. It only generates and explains the expression text — you paste that into your own crontab or scheduler.
Is my data sent anywhere?
No. The expression is built and described entirely in your browser.
