Common questions
Cron expression FAQ
What is a cron expression generator?
It builds standard five-field cron strings from presets or custom rules, then shows a plain-English schedule so you can paste into crontab, GitHub Actions, Kubernetes, or other schedulers.
How do I generate a cron expression for a daily job?
Choose Daily at midnight or Daily at 9:00, or set Minute and Hour to fixed values and leave Day of month, Month, and Day of week as Every (*).
Is this the same as a cron job expression generator for Linux?
Yes for classic Unix crontab (five fields). Some platforms add a seconds field (six fields) — this tool outputs the common five-field format.
Can I explain an existing cron string?
Switch to Explain mode, paste any five-field expression, and read the human-readable description powered by cronstrue.
Are schedules sent to a server?
No. Expressions are built and described entirely in your browser.
What do day-of-week numbers mean?
0 = Sunday through 6 = Saturday in standard Unix cron. Ranges like 1-5 mean Monday through Friday.
