Five-field POSIX cron: minute, hour, day of month, month, day of week.
Builder Controls
Use presets, then fine tune the fields directly.
Generated Snippet
Deployment-ready starter for the selected platform.
Compose a five-field cron expression, preview runs in African time zones, and export snippets for Linux crontab, GitHub Actions, Kubernetes CronJobs, or AWS EventBridge with the warnings developers usually learn the hard way.
EventBridge scheduled rules use six fields wrapped in cron(...), including a year field. It also requires a question mark in either day-of-month or day-of-week when the other field is constrained. This builder converts simple five-field schedules and flags ambiguous cases.
They are a browser-side preview based on the selected timezone and common cron semantics. Always verify in the target scheduler before production, especially around daylight saving changes, missed runs and platform-specific retry behavior.
The most common mistake is assuming every platform uses the same timezone and day matching rules. GitHub, Kubernetes, Linux cron and EventBridge all have their own deployment details.
