Cron expression for Every day at 6am

What people actually schedule with 0 6 * * *

• Generating and emailing the daily standup / overnight-activity report so it's waiting when the team opens their laptop
• Cron-driven static site or sitemap rebuilds so search engines and readers get fresh content first thing
• Kicking off morning batch jobs (invoice generation, order routing) that should complete before the business day opens

Use 0 6 * * * on your platform

It’s the same 5-field expression everywhere — what changes is where you put it and which timezone it runs in.

Linux / crontab

0 6 * * * /path/to/your-command

Runs in the server’s local timezone — check it with timedatectl. Full field reference: crontab(5) man page.

GitHub Actions

on:
  schedule:
    - cron: "0 6 * * *"

GitHub Actions always runs scheduled jobs in UTC — there is no timezone setting, and runs can be delayed under load (official docs).

Kubernetes CronJob

spec:
  schedule: "0 6 * * *"

Defaults to UTC. Set spec.timeZone (Kubernetes 1.27+) for a specific zone — see the CronJob docs.

Quartz / Spring @Scheduled

Quartz uses 6 fields (seconds first): 0 0 6 * * *. Watch out: Quartz day-of-week is 1=SUN … 7=SAT (not 0–6), and day-of-month / day-of-week use ? — double-check if your schedule touches those fields (Quartz cron reference).

Gotchas with every day at 6am schedules

• 6am is right on the cusp of business hours — there's no slack left. Anything that overruns now competes directly with arriving users and early-shift staff. Wrap with both a lock and a timeout (flock -n /tmp/morning.lock timeout 20m ...) so a slow run can't pile onto live traffic.
• "6am" drifts badly across server time zones. A job set to 0 6 * * * on a UTC box fires at 1am US-Eastern and 3pm in Tokyo — "morning report" becomes a 1am surprise. Pin the intended zone explicitly (CRON_TZ=America/New_York in the crontab, or set the unit's Timezone=) rather than relying on the host's clock.
• Email sent at 6am can get buried before anyone reads it. Fire-and-forget reports at 6am land before login, then get pushed down by 7–9am newsletters and notifications. If open rate matters, hold delivery to the recipient's local 8–9am, or have the job write the report and queue the send separately.

Is 0 6 * * * the right schedule?

If the report only needs to be read, not generated at a specific moment, every weekday at 9am skips weekends nobody reads and lands at peak attention. If it's heavy batch work, move the compute to 4am and leave only the lightweight send at 6.

• Every day at 7am 0 7 * * *
• Every day at 8am 0 8 * * *
• Every day at 10am 0 10 * * *
• Every day at 11am 0 11 * * *
• Every day at 1pm 0 13 * * *
• Every day at 2pm 0 14 * * *
