Kubernetes uses the same five fields. Set spec.timeZone (stable since Kubernetes 1.27), otherwise the schedule follows the time zone of kube-controller-manager.

Workflow schedules use five-field cron in UTC and run only from the default branch. Runs at minute 0 are the most likely to be delayed or dropped when GitHub is busy; an odd minute such as 7 or 23 starts more reliably.

The equivalent OnCalendar= value is Mon..Fri *-*-* 09..17:00:00.
Check it with systemd-analyze calendar 'Mon..Fri *-*-* 09..17:00:00', which prints the next elapse time. Persistent=true runs a missed job after downtime, which classic cron never does.

EventBridge rules take six fields (minute, hour, day-of-month, month, day-of-week, year) in UTC; EventBridge Scheduler can use a time zone. One of day-of-month and day-of-week must be ?, and day-of-week runs 1-7 from Sunday, so names are used here.
cron(0 9-17 ? * MON-FRI *)
Quartz adds a leading seconds field and needs ? in either day field; days of the week are 1 (SUN) to 7 (SAT).
0 0 9-17 ? * MON-FRI
Spring's @Scheduled(cron = ...) also uses six fields, but numbers days of the week 0-7 with Sunday as 0 or 7, like Unix cron; the names shown above work in both.
