Cron Generator and Preview
Build a cron expression and preview the next runs for a stated dialect and zone, without scheduling anything.
Common schedules
Five fields: minute hour day month weekday. Lists (1,15), ranges (1-5), steps (*/10), names (MON, JAN), and @daily-style shortcuts work.
Nothing is scheduled from this page. Servers usually run cron in UTC or their own zone, so check which one yours uses.

Tool details and privacy
Pick a common schedule or build the expression field by field, then read its meaning in a plain sentence and see the next six run times.
Five fields in a row like 0 9 * * 1-5 are easy to get wrong; seeing the meaning and the times confirms you wrote what you meant.
Options
- Lists (1,15), ranges (1-5), steps (*/10), names (MON, JAN), and @hourly, @daily, @weekly, @monthly, and @yearly are read; 7 also means Sunday.
- When both day of month and weekday are set, the job runs on either, as cron does.
- Times are worked out in your device time or in UTC.
Limits
- Nothing is scheduled from this page.
- A schedule that never happens within five years (such as 30 February) is reported as never running.
- Non-standard fields such as L, W, #, or a seconds field are not read.
Privacy
What you type stays in your browser. Nothing is uploaded or saved on the server.
