Frequently Asked Questions
How is Quartz Scheduler different from standard Linux cron?
Quartz Scheduler differs from Linux cron in field count, day-of-week numbering, or supported special characters — see the Quick Reference table above for the exact differences.
Can I convert a Linux cron expression to Quartz Scheduler automatically?
Yes — paste it into the multi-platform Cron tool above (or on the main Cron Editor page) and switch to the Quartz Scheduler tab to get the equivalent expression instantly.
Does Quartz Scheduler support L, W, or # ?
Yes. Quartz Scheduler supports L (last day of month) and # (nth weekday of month, e.g. "MON#1" for the first Monday).
Does Quartz Scheduler run on my local timezone or UTC?
Quartz Scheduler evaluates schedules in whatever timezone you configure (or the system/server timezone if none is set) — it isn't fixed to UTC.
