How do I convert a cron expression to AWS EventBridge?

AWS EventBridge uses either cron() or rate() expressions. Convert by wrapping your expression: cron(0 5 * * ? *). Note: AWS uses 6 fields (adds year) and uses ? instead of * for day-of-week or day-of-month.

What's the difference between cron and AWS EventBridge scheduling?

AWS EventBridge cron uses 6 fields (adding year) and requires ? in either the day-of-month or day-of-week field. Rate expressions (e.g., rate(1 hour)) are simpler for fixed intervals.
