Good to know

The last run of the day is at 17:45, because the hour field 9-17 includes every minute of 17:00–17:59.

Use it in crontab, GitHub Actions, Kubernetes and Node.js

crontab (crontab -e):

*/15 9-17 * * 1-5 /usr/local/bin/my-job.sh >> /var/log/my-job.log 2>&1

GitHub Actions (times are UTC):

on:
  schedule:
    - cron: '*/15 9-17 * * 1-5'

kind: CronJob
metadata:
  name: my-job
