How to use
- Read the expression and the English meaning above. Confirm they match the job you have in mind.
- Use the time zone dropdown to preview the next 10 fire times in UTC or a US/EU city.
- Copy the expression into crontab, GitHub Actions (`on.schedule.cron`), or your job runner.
- If you need a nearby interval, browse the related schedules at the bottom of this page.
Nine in the morning is when a lot of office-hour automations start: stand-up summaries, store-open checks, “here is last night’s error budget.” Hour 9, minute 0, every calendar day.
If you do not want Saturday and Sunday, switch to 0 9 * * 1-5. This page keeps the seven-day version so the difference is obvious.
When this schedule is a good fit
Typical uses: A morning briefing email; Pre-warming caches before traffic arrives; Opening a feature flag window.
Cron fields are zone-naive. The daemon’s TZ — or the TZ= line above the job — decides what “midnight” or “9am” means. Preview both UTC and the office zone before you ship.
FAQ
Does this run on weekends?
Yes. Add 1-5 in the day-of-week field to skip Saturday and Sunday.
9am in which zone?
The daemon’s zone. If the server is UTC and you want 9am in Berlin, either set TZ=Europe/Berlin for that crontab or convert the hour.
Does this page upload my crontab?
No. The explainer and the next-run list run in your browser. The expression on this page is a public example.
