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.

AWS EventBridgeEventBridge weekdays are 1–7 (1 = Sunday) and one day field must be ?.

Quartz (Java)Seconds first; weekdays 1–7 with 1 = Sunday.

Running a job every 15 minutes during business hours (Mon–Fri, 9am–5pm)

What is the cron expression for every 15 minutes during business hours (Mon–Fri, 9am–5pm)?

*/15 9-16 * * 1-5. In plain English: every 15 minutes, between 09:00 AM and 04:59 PM, Monday through Friday. It works in standard 5-field cron — Linux crontab, Kubernetes and GitHub Actions.

How do I schedule a job every 15 minutes during business hours (Mon–Fri, 9am–5pm) in AWS EventBridge?

Use cron(0/15 9-16 ? * 2-6 *). 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 "*/15 9-16 * * 1-5" 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.
