Build, validate, and preview cron expressions across Unix, AWS EventBridge, GitHub Actions, Vercel, Kubernetes, Quartz, and Spring — with timezone-correct next-run previews.

Dialect

Spring @Scheduled

Build Spring Framework @Scheduled cron expressions with the 6-field syntax, the zone attribute, and Spring-specific quirks.

Last verified: 2026-05-15

Six fields, Spring-flavored Quartz

Spring's @Scheduled(cron = ...) uses a 6-field expression: second minute hour day-of-month month day-of-week. There is no year field — the seventh column found in classic Quartz is not supported here.

@Scheduled(cron = "0 0 9 * * MON-FRI", zone = "Europe/Berlin")
public void morningKickoff() { /* ... */ }

The zone attribute

Spring honors a zone attribute on @Scheduled that accepts any IANA zone identifier. Without it, schedules run in the JVM's default timezone — which is rarely what you want in a containerized deployment, where the container often defaults to UTC.

Day-of-week numbering subtleties

Spring historically used 0-6 (Sun-Sat) but switched to 1-7 (Mon-Sun) as part of moving to Quartz-style parsing. As of Spring 5.3+, the supported numbering is 1 = MON, 7 = SUN — which is yet another convention, different from both Unix (0=SUN) and AWS/Quartz (1=SUN). Use the alphabetic form (MON-FRI) for unambiguous schedules.

cron.expression properties

Hardcoded cron strings rot fast. Externalize them to application.properties with @Scheduled(cron = "$${my.cron}") so deployment-time tuning doesn't require a recompile. The default property-placeholder resolver handles this directly.

Spring vs. classic Quartz subtleties

  • Spring does not support the ? character — use * instead.
  • Spring does not support L, W, or # — for those, integrate Quartz directly.
  • Spring accepts a special - value meaning "never run", used to disable a scheduled task via configuration.
