How to Build Cron Expressions
Step-by-step guide to creating cron schedules for jobs and automation — with visual builder and next-run preview.
Cron expressions define when scheduled jobs run. Standard cron uses 5 fields: minute, hour, day of month, month, and day of week.
Common patterns
- * — every value
- */5 — every 5 units
- 1-5 — range (Mon–Fri for weekday)
- 0 9 * * 1-5 — 9 AM on weekdays
- 0 0 1 * * — midnight on the 1st of each month
Build tab in the Cron workbench
Use presets (every minute, hourly, daily, weekly, monthly) or set each field manually. The expression updates live and the Parse tab shows the next 5 runs so you can confirm the schedule before deploying to Kubernetes or crontab.
