About this tool

Enter a standard 5-field cron expression to instantly see what it means in plain language and when it will next fire. Cron is the Unix job scheduler — it triggers commands at fixed times or intervals using a compact notation.

Common expressions

Expression	Meaning
`* * * * *`	Every minute
`0 * * * *`	Every hour on the hour
`0 0 * * *`	Daily at midnight
`/15 * * *`	Every 15 minutes
`0 9 * * 1-5`	Weekdays at 9:00 am
`0 0 1 * *`	1st of every month at midnight
`0 0 * * 0`	Every Sunday at midnight

Note on day-of-month vs day-of-week: When both fields are restricted (neither is *), most cron implementations match if either condition is true (OR logic), not both.
