Spring @Scheduled Cron Expression Guide
Spring @Scheduled uses Quartz-style 6-field cron expressions with a seconds field prepended. The builder generates the exact @Scheduled(cron = "...") annotation for copy-paste into your Spring component.

Spring @Scheduled uses the same 6-field Quartz format. The annotation goes on a @Component method.

How do I use @Scheduled in Spring Boot? ▾
Add @EnableScheduling to your @SpringBootApplication class, then annotate a method in a @Component or @Service with @Scheduled(cron = "0 0 9 * * MON-FRI"). The method must be void and take no arguments.
Does Spring @Scheduled use 6 or 7 fields? ▾
Spring @Scheduled supports 6-field Quartz-style expressions (second minute hour dom month dow). Unlike Quartz itself, the year field is generally not supported in Spring's default cron parser.
Does Spring @Scheduled support timezone? ▾
Yes — Spring 4.0+ supports @Scheduled(cron = "0 0 9 * * MON-FRI", zone = "America/New_York"). The zone parameter accepts any valid IANA timezone ID.
What does @Scheduled(fixedRate = ...) do vs cron? ▾
"fixedRate" runs the method every N milliseconds after the previous start time, regardless of how long the method takes. "cron" fires at specific calendar times. Use cron for calendar-based schedules; use fixedRate or fixedDelay for interval-based polling.
How do I make Spring @Scheduled not overlap itself? ▾
By default, @Scheduled is single-threaded per task in Spring Boot. To prevent overlap, keep it single-threaded (default) or add @Async + a custom TaskScheduler with a thread pool, combined with a distributed lock (Shedlock) for multi-instance deployments.
