What this tool does
This builder helps you create a cron expression — the five-field schedule used by Unix cron, CI pipelines and many schedulers. Choose a common schedule or type your own, and see a human-readable description to confirm it means what you intend.
The five fields
- Minute (0–59), Hour (0–23)
- Day of month (1–31), Month (1–12)
- Day of week (0–6, Sunday = 0)
