| Day of month | * | Which day of the month to run (1-31) |
| Month | * | Month of the year (1-12 or JAN-DEC) |
| Day of week | * | Day of the week (0-6 or SUN-SAT) |

(e.g. MON,WED,FRI), hyphens for ranges (9-17), and slashes for steps
(*/5).
Cron is one of the most widely used schedulers for automating jobs across Linux servers, data pipelines, and cloud platforms. A five-field cron expression lets you pinpoint the minute, hour, day of the month, month, and day of the week when a job should run. This builder focuses on that common format so you can verify schedules quickly without memorising every shortcut.
Here are some quick examples:
0 2 * * * — Run every day at 2:00 AM.*/10 * * * MON-FRI — Run every 10 minutes on weekdays.30 9 1 * * — Run at 9:30 AM on the first day of every month.0 12 L * * — Run at noon on the last day of the month.Need to share the schedule? Copy the expression with one click and paste it into cron, Kubernetes, Airflow, or any other scheduler that accepts standard cron syntax.
