Noon jobs are for things people should see after lunch: a sales snapshot, a queue depth mail, a “still broken?” canary. Hour 12, minute 0.
In UTC, 12:00 is midday in London in winter and 7:00 or 8:00 on the US East Coast depending on daylight saving. Always name the zone in the runbook.
When this schedule is a good fit
Typical uses: A mid-day operations email; Refreshing a public status badge; Kicking a batch that should not collide with the midnight warehouse load.
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.
