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 quarter (Jan, Apr, Jul, Oct 1st)

What is the cron expression for every quarter (Jan, Apr, Jul, Oct 1st)?

0 0 1 1,4,7,10 *. In plain English: at 12:00 AM, on day 1 of the month, only in January, April, July, and October. It works in standard 5-field cron — Linux crontab, Kubernetes and GitHub Actions.

How do I schedule a job every quarter (Jan, Apr, Jul, Oct 1st) in AWS EventBridge?

Use cron(0 0 1 1,4,7,10 ? *). 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 1 1,4,7,10 *" 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.
