Cron expression syntax
A standard cron expression has five fields, separated by spaces:
┌──────── minute (0–59) │ ┌────── hour (0–23) │ │ ┌──── day of month (1–31) │ │ │ ┌── month (1–12) │ │ │ │ ┌─ day of week (0–6, Sunday = 0) │ │ │ │ │ * * * * *
Common operators
*— every value in the field.,— list, e.g.1,15,30.-— range, e.g.9-17./— step, e.g.*/5means "every 5".
What does 0 9 * * 1-5 mean?
Run at 09:00 on weekdays (Monday through Friday).
Does this support seconds (6-field cron)?
No. This builder targets the standard 5-field cron used by Unix crontab, GitHub Actions, and most CI systems. Quartz (Java) and Spring use a 6-field variant with seconds — those are not generated here.
Where can I run a cron job?
Linux/macOS: crontab -e. Cloud schedulers that accept cron syntax include GitHub Actions, AWS EventBridge, Google Cloud Scheduler, Vercel Cron, and Cloudflare Workers Triggers.
