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 on the 15th of every month?
0 0 15 * *. In plain English: at 12:00 AM, on day 15 of the month. It works in standard 5-field cron — Linux crontab, Kubernetes and GitHub Actions.How do I schedule a job on the 15th of every month in AWS EventBridge?
Use
cron(0 0 15 * ? *). 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 0 15 * *" 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.
