Tips

✔EventBridge cron has 6 fields (min, hr, dom, month, dow, year). Standard has 5.
✔Use ? for day-of-month or day-of-week when the other is specified in EventBridge.
✔rate() is simpler for fixed intervals; cron() for specific schedules.
✔All EventBridge times are in UTC.

Build scheduled workflows hands-on

Deploy EventBridge scheduled rules and Lambda cron jobs in real AWS infrastructure.
