Cron Next Runs Guide

Cron is a way to say when a task should run. A schedule has five parts: minute, hour, day of the month, month, and day of the week. Cron Next Runs shows upcoming times so you can check a schedule before using it.

Try a daily schedule

Type 0 9 * * * into Cron expression. Read it from left to right: minute 0, hour 9, then * for any day, any month, and any weekday. Choose UTC under Timezone. The upcoming rows should be at 09:00 UTC each day. The exact dates depend on when you open the page; the tool only shows times after now.

Switch Timezone to Local (this device). The schedule is now read using your device’s time zone, so the underlying moments may change. Count controls how many future dates you see, not how often the task runs.

If you see an error or an odd date

Make sure there are exactly five parts separated by spaces. 0 9 * * is missing one part. The tool understands * (every allowed value), 1,2 (a list), 1-5 (a range), and */15 (steps of 15). It previews a schedule in your browser; it does not install a job or check your server’s time zone.

Important limitation: do not rely on this page to check schedules restricted to only a weekday or only a day of the month. Its current day-matching logic can list extra dates in those cases. Check such schedules with your actual cron implementation before deploying them.

Where your input goes

Processing runs in your browser. The tool does not upload your input to ilham.dev.

Questions you might have

How are day-of-month and weekday combined?: This preview uses an OR between the day-of-month and weekday fields. That is useful to know, but its current logic can also list extra dates when one of those fields is * and the other is restricted. For schedules like “weekdays only”, verify the dates using the cron implementation on your server rather than relying on this preview alone.
