Cron Expressions
QuzenixCron uses the standard 5-field Unix cron syntax — the same format as a Linux crontab. If you're new to it, start with the presets in the form and work your way from there.

Minimum interval limits
Minimum interval depends on your plan: Free is 30 minutes, Pro is 1 minute, Business is 30 seconds. The form will reject any expression faster than your plan allows.Validation
As you type a cron expression, QuzenixCron parses it in real time using cron-parserand shows a human-readable description plus the next 5 scheduled runs. If the expression is invalid, you'll see an error before submitting.
