Why use this schedule
The fastest schedule most cron systems allow. It suits near-real-time polling where waiting five minutes is too slow.
- Polling a queue or an inbox for new work
- Heartbeat pings to an uptime monitor
- Flushing a small in-memory buffer to disk
First runs, as an example
Starting from 1 January 2027, evaluated in UTC:

Ready-to-use Quartz config
Drop this into your project. The expression is the one above.
Trigger trigger = TriggerBuilder.newTrigger()
.withIdentity("myTrigger", "group1")
.withSchedule(CronScheduleBuilder.cronSchedule("0 * * * * ?")
.inTimeZone(TimeZone.getTimeZone("UTC")))
.build();The Quartz fields, in order: second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (1-7, 1 = Sunday), year (1970-2199, optional).
Things to watch out for in Quartz
- 0/N and */N both work, but the schedule restarts at the start of each hour, so N should divide 60 for even gaps.
- Quartz uses the JVM default time zone unless you set one: CronScheduleBuilder.cronSchedule(expr).inTimeZone(TimeZone.getTimeZone("UTC")).
The common mistake with this schedule
A job that takes longer than one minute will overlap with the next run. Guard against it with a lock, Quartz @DisallowConcurrentExecution, or concurrencyPolicy: Forbid in Kubernetes.
