Why use this schedule
One run at the top of each hour, twenty-four a day. This is the classic maintenance cadence: frequent enough to keep data fresh, slow enough that even a heavier job finishes comfortably before the next one starts.
- Rotating or compressing logs
- Hourly aggregation of events
- Refreshing materialised views

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 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
- Six fields: seconds first, then minute, hour, day-of-month, month, day-of-week. Use 0 in seconds to fire at the start of the minute.
- Quartz uses the JVM default time zone unless you set one: CronScheduleBuilder.cronSchedule(expr).inTimeZone(TimeZone.getTimeZone("UTC")).
The common mistake with this schedule
Many teams start everything at minute 0, which creates a thundering herd on shared systems. Offset heavy jobs, for example to minute 7 or 23, or use H in Jenkins.
