The same schedule on every platform
The five fields mean the same thing everywhere, but each scheduler wraps them differently — and AWS and Quartz number weekdays from 1 (Sunday), not 0.

What is the cron expression for every Sunday at 3am?
0 3 * * 0. In plain English: at 03:00 AM, only on Sunday. It works in standard 5-field cron — Linux crontab, Kubernetes and GitHub Actions.How do I schedule a job every Sunday at 3am in AWS EventBridge?
Use
cron(0 3 ? * 1 *). EventBridge needs six fields (a year at the end), a ? in one of the day fields, and numbers weekdays 1–7 starting on Sunday.What timezone does "0 3 * * 0" run in?
Cron uses the server's timezone. Kubernetes CronJobs default to the controller's timezone (set
spec.timeZone on 1.27+), GitHub Actions and AWS EventBridge rules always use UTC. Use the timezone picker above to see the next runs in your own time.
