Frequently Asked Questions

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. Named days and months are supported.
What does '*/15' mean?
The '*/n' syntax means 'every nth value'. So '*/15' in the minute field means every 15 minutes (0, 15, 30, 45).
How do I run something at midnight?
'0 0 * * *' runs at midnight every day. The tool can help you build expressions for any schedule using the visual builder.
