Things to watch out for in AWS EventBridge
- Weekdays are 1-7 with Sunday as 1, or use SUN-SAT names. Monday to Friday is 2-6.
- Six fields with a required year: minute, hour, day-of-month, month, day-of-week, year. There is no seconds field.
- EventBridge rules always run in UTC. If you want a local time zone with DST support, use EventBridge Scheduler instead.
The common mistake with this schedule
The minute comes first, then the hour. 30 8 means 08:30, while 8 30 would be an invalid hour.
