Why use this schedule
Twelve runs a day, at even hours (00:00, 02:00, 04:00 and so on). It halves the load of an hourly job while still catching changes within a couple of hours.
- Pulling analytics exports
- Rebalancing a recommendation cache
- Checking certificate expiry

Ready-to-use Spring config
Drop this into your project. The expression is the one above.
@Scheduled(cron = "0 0 */2 * * *", zone = "UTC")
public void runJob() {
// ...
}app.job.cron=0 0 */2 * * *
# @Scheduled(cron = "${app.job.cron}")The Spring fields, in order: second (0-59), minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-7, 0 and 7 = Sunday).
Things to watch out for in Spring
- The expression has six fields, so */15 in the minutes position still needs a leading 0 for seconds, or the job fires every second of those minutes.
- Spring uses six fields (no year). The leading 0 is the seconds field.
- Spring evaluates in the server time zone by default. Add zone = "UTC" (or any ZoneId) to @Scheduled to make it explicit.
The common mistake with this schedule
The step restarts at midnight, so */2 always means the even hours. If you need odd hours use 1-23/2.
