Usage guide

Build a five-field cron schedule and verify when it will run

Cron expressions are compact but easy to misread, especially around day-of-week, day-of-month, ranges, and step values. Generate a schedule only after deciding the exact time zone and recurrence expected by the system that will execute it.

How to use Cron Expression Generator

1.Choose the minute, hour, day-of-month, month, and day-of-week pattern you need.
2.Read the generated plain-language description and compare it with your intended schedule.
3.Check the hosting platform's cron syntax and time-zone rules before deploying the expression.

Examples

0 9 * * 1 can represent 09:00 every Monday in a standard five-field cron implementation.
*/15 * * * * commonly represents every 15 minutes.
0 0 1 * * commonly represents midnight on the first day of each month.

Limitations and notes

Cron implementations differ; some add a seconds field, use different day-of-week numbering, or evaluate schedules in UTC.
A scheduled expression says when a job should be triggered, not whether the previous run completed successfully.

Why does my cron run at the wrong local time?

The scheduler may use UTC or another configured time zone. Confirm the platform's time-zone setting before changing the expression.

Do all cron services use five fields?

No. Some use six or seven fields or proprietary syntax, so always check the documentation for the system running the job.
