How to use it
- Copy 0 9 * * 1-5 into any five-field scheduler; the 1-5 range reads Monday through Friday in classic numbering.
- Decide which 09:00 you mean — read the timezone note before this line ships to a UTC platform like GitHub Actions.
- Shift start-of-day per region by editing the hour in the tester: 0 8 * * 1-5 for 08:00, 30 9 * * 1-5 for 09:30.
0 9 * * 1-5 is the business-hours opener: 09:00, Monday through Friday, weekends skipped by construction — standup reminders, market-hours polls, workday reports. The preview shows one clean working week; the notes cover the timezone question every 9am job meets, and the dialect rows translate the range.

Gotchas worth knowing
09:00 where, exactly?
A workflow schedule reads this line as 09:00 UTC — London-ish mornings, small hours in California. spec.timeZone pins the intent on Kubernetes 1.27+; plain crontabs follow their host. Zone-shifted variants, DST included, come from the cron timezone converter.
Common errors
Field 5 (day of week): "5-1" runs backwards — ranges go from low to high.- Ranges never run downhill or wrap — 5-1 is refused with the token marked rather than guessed at. Spell spans low to high: 1-5 for the working week, or a list like 5,6,0 across Sunday.
FAQ
Does this line skip public holidays?
No — cron knows weekdays, not holiday calendars: 1-5 fires every Monday-to-Friday including December 25th. Holiday awareness lives in the job or the platform invoking it.
Why five runs on consecutive dates?
A full working week follows the preview's Saturday start: Monday August 3rd through Friday the 7th — weekends structurally absent, not filtered.
How does daylight saving affect a 9am schedule?
On a UTC platform the UTC hour never moves — your local 09:00 does, twice a year. Zone-aware schedulers shift with the wall clock; the converter's dual-expression table shows the dates.
