Build Cron Expressions Visually
Cron syntax is powerful but cryptic — 0 9 * * 1-5 means "9am on weekdays," but good luck remembering that when you need to write one at 2am during an incident. This generator lets you build cron expressions from dropdown menus and presets, showing the human-readable explanation alongside the cron string.
How to Use
- Pick a preset from the list, or configure each field individually from the dropdowns.
- The cron expression and its plain-English explanation update in real time.
- Click Copy to copy the expression — ready for crontab, Kubernetes CronJob, GitHub Actions schedule, or any other cron-compatible system.
