Cron is a scheduler that uses five fields: minute, hour, day of month, month, and day of week. Crontab Generator assembles those five fields and writes a rough English description. It does not schedule a job, check future run times, or support special strings like @reboot.
Pick a preset
Choose Every 5 minutes under Preset. Expression should read */5 * * * *, meaning minutes divisible by five in each hour. Copy takes only that expression, not a command to run. Choose Weekdays at 09:00 to see 0 9 * * 1-5; note that the time is interpreted by your cron environment, not this page.
You can also edit Minute, Hour, and the other fields yourself, but this builder does not validate the values: 99 in Minute would still appear in the output. Check the syntax and timezone in the scheduler you actually use before installing a job. For times that cross daylight-saving changes, test the schedule in its intended timezone.

Questions you might have
- Is `0 0 * * *` always midnight UTC?
- No. It means midnight according to the cron implementation’s configured timezone, often the host’s local timezone. This tool does not read that setting or convert times to UTC.
- Does this schedule the job?
- No. It only builds and explains the expression. Nothing is scheduled and nothing runs.
