What cron format is supported?

The tool supports standard 5-field cron (minute, hour, day-of-month, month, day-of-week) and extended 6-field cron with seconds. Both Unix cron and Quartz scheduler syntax are handled.

Can I see when the next runs will occur?

Yes. The tool displays the next 10 execution times based on your current timezone, so you can verify exactly when the job will fire.

Is this tool accurate for all timezones?

The next-run calculations use your browser's local timezone by default. You can also select a specific timezone to see execution times in a different region.
