Frequently Asked Questions
How do I run this only on weekdays?
Change the day-of-week field to `1-5`: `0 6 * * 1-5` fires Monday through Friday at 6 AM.
0 6 * * * in Quartz / Spring
This trigger fires once per day at 06:00 in the trigger's timezone — early enough to beat the workday, late enough that overnight pipelines have usually landed their data. It is a favorite slot for morning digest jobs.

Field Breakdown
Using It with Quartz / Spring
Morning digests, dashboard pre-warms, and overnight-results summaries are the classic 6 AM workload, and because the output is read by humans in a particular region, the timezone matters more than for most schedules. Spring lets you pin it with @Scheduled(cron = "0 0 6 * * ?", zone = "America/Chicago"); in plain Quartz, call inTimeZone() on the CronScheduleBuilder. Anchored to a named zone, the 6 AM promise survives both DST changes and the application being rehosted to a data center on another continent.
Quartz-Specific Notes
- →Without an explicit zone, the 6 means 06:00 in the JVM default timezone — a digest that suddenly arrives at midnight is the signature symptom of a container that switched to UTC.
- →If the digest pulls from data written by overnight jobs, validate freshness inside the job; the 06:00 fire time says nothing about whether upstream work actually completed.
- →Quartz also accepts a 7-field form with a trailing year, but for a plain daily schedule the optional year field adds nothing and is normally omitted, as here.
Frequently Asked Questions
Can one trigger send each user their digest at 6 AM in their own timezone?
No — a CronTrigger evaluates against exactly one TimeZone. Per-user local delivery needs either one trigger per zone (there are fewer distinct offsets than you'd think) or a frequent trigger whose job selects the users whose local time just crossed 06:00.
Why did my 6 AM job start arriving at 1 AM after we moved to Kubernetes?
The new pods almost certainly default to UTC, and 06:00 UTC is 1 AM in US Central daylight time. Set zone on @Scheduled or a TimeZone on the trigger instead of relying on the host clock.
0 6 * * * in AWS EventBridge
This schedule fires once a day at 06:00 UTC, which lands at 07:00 or 08:00 across central Europe — squarely in the get-ready-for-work window. That makes it a favorite anchor for jobs whose output should be sitting in a European inbox or dashboard when the workday opens.

Unix / POSIX equivalent: 0 6 * * *
Field Breakdown
Using It with AWS EventBridge
Define it with aws scheduler create-schedule and point the schedule at a Lambda that assembles the morning digest, renders it, and hands it to SES for delivery. Other common occupants of this slot are QuickSight dataset refreshes timed so the first viewer of the day sees current numbers, and cache pre-warming sweeps that replay yesterday's hottest queries against the API before traffic ramps. With one run per day the cost story is trivial, so teams often hang several light morning chores on the same trigger rather than minting separate schedules.
AWS-Specific Notes
- →06:00 UTC corresponds to 07:00 CET in winter and 08:00 CEST in summer — the run drifts an hour against the European wall clock twice a year unless you move it to EventBridge Scheduler with a timezone.
- →For the US East Coast this is a 01:00–02:00 wake-up, so treat it as a late-night slot there, not a morning one.
- →The hour field accepts lists, so widening this to a morning-and-evening pair is a one-character-class edit: cron(0 6,18 * * ? *).
Frequently Asked Questions
Can one schedule deliver a 6 AM digest to users in several timezones?
No single cron line can; 6 AM means a different UTC instant per zone. Create one Scheduler schedule per audience timezone, each with ScheduleExpressionTimezone set, or fire once and let the application defer per-user delivery.
Will the trigger arrive at exactly 06:00:00?
EventBridge promises invocation within the scheduled minute, and under load it can slip up to a minute beyond that. If the digest job itself takes a few minutes, start counting your delivery SLA from about 06:02.
How do I confirm the rule actually fired this morning?
Check the rule's Invocations and FailedInvocations metrics in CloudWatch, or query the target Lambda's logs for the scheduled-event payload — its time field will read 06:00:00Z for that date.
0 6 * * * in GitHub Actions
One run every day at 06:00 UTC. That maps to 07:00 in Central Europe in winter and 08:00 in summer, which is why this schedule shows up so often in front of European workdays — and to a fixed 15:00 in Tokyo, since Japan never shifts its clocks.

Field Breakdown
Using It with GitHub Actions
Declared as on: schedule: - cron: "0 6 * * *" in a workflow on the default branch, the 6am-UTC slot typically prepares things people will read over coffee: compiling an overnight-activity digest of issues and PRs, refreshing the data behind a morning dashboard, or opening the day's triage issue before a European team logs in. The job has the whole quiet overnight window behind it, so pulling from external APIs that were busy during the US evening is usually painless by this hour. Whatever it produces should be tolerant of arriving a few minutes past six, because scheduled starts drift.
GitHub-Specific Notes
- →Local arrival in DST-observing Europe alternates between 07:00 and 08:00 across the year; in Japan it is 15:00 every single day, because there is no DST to move it.
- →A skipped or failed run is not retried by the scheduler — the next attempt is 24 hours away, so morning-report jobs benefit from a failure notification step.
- →06:00 UTC is the middle of the night for all of the Americas (01:00 or 02:00 Eastern), which makes this a poor choice for US-audience morning content despite the friendly-looking hour.
Frequently Asked Questions
Can I make this fire at 6am London time all year?
Not with one cron line — London is UTC in winter and UTC+1 in summer. Either schedule both 0 5 * * * and 0 6 * * * and have a first step exit unless TZ=Europe/London date +%H prints 06, or accept the one-hour seasonal drift.
My 6am digest sometimes arrives at 6:08 — is that a configuration problem?
No. Scheduled workflow starts are queued and routinely begin several minutes after the nominal time. If a hard deadline exists downstream, schedule earlier rather than expecting punctuality.
