Frequently Asked Questions

Everything you need to know about Cron expressions, syntax rules, and platform nuances.

Why does Spring Boot use 6 fields instead of 5?

Spring Framework schedules support second precision, placing a second field (0-59) at index 0 before minute, hour, day-of-month, month, and day-of-week.

How do I specify timezones in Spring @Scheduled?

Use the zone attribute inside the annotation, e.g. @Scheduled(cron = "0 0 9 * * 1-5", zone = "America/New_York").
