Cron Expression Explainer: Plain English and Next Run Times
Paste a cron expression to see what it means in plain English and when it will run next. Checks ranges, steps, names and @daily-style shortcuts.
Type a five-field cron expression, such as */5 * * * *, or a shortcut like @daily. You get a plain English sentence, a clear error if something is wrong, and the next five run times in your browser’s time zone.
Frequently asked questions
- What do the five cron fields mean?
- In order: minute, hour, day of month, month and day of week.
- What happens when both day fields are set?
- Standard cron runs the job when either one matches. For example, 0 0 1 * 1 runs on the 1st of the month and on every Monday.
- Which time zone does cron use?
- The server’s time zone. The next run times here use your browser’s time zone, so they can differ from your server.
- Does it support @reboot and @daily?
- Yes for the common shortcuts. @reboot has no schedule: it runs once when the system starts.
