Cron Expression Generator은(는) 무엇을 하나요?
Cron Expression Generator은(는) 브라우저에서 결과 생성을(를) 수행하며 결과와 제한을 명확히 설명합니다. 검증된 기능: Cron validation, Next five runs, IANA time zones, Plain-language summary.
Cron syntax is not fully portable
Use this parser for conventional five-field schedules. Before deployment, confirm how the target system combines day-of-month with day-of-week, handles time zones, and treats daylight-saving transitions.
사용 방법
- Enter a five-field expression directly or edit Minute, Hour, Day, Month, and Weekday separately.
- Choose the IANA time zone in which the schedule should be interpreted.
- Select Calculate and review the plain-language summary plus the next five runs.
실제 입출력 예시
Run at 09:00 on weekdays
입력
0 9 * * 1-5출력
at minute 0, at hour 9, on weekdays. Day-of-month: *; month: *.
Next runs: five instants in the selected time zoneThe page uses the Unix-style order minute, hour, day of month, month, and day of week.
일반적인 오류와 해결 방법
| 현상 | 가능한 원인 | 해결 방법 |
|---|---|---|
| The expression is rejected even though another scheduler accepts it. | The other system may use six or seven fields, Quartz syntax, macros, or vendor extensions. | Translate the schedule to five fields and verify the target scheduler’s documented dialect. |
| A run shifts or occurs twice near a daylight-saving change. | Local clock times can be skipped or repeated when a zone changes offset. | Review the preview in the deployment time zone and prefer UTC for schedules that require uniform elapsed intervals. |
Important behavior of Cron Generator
이 도구의 구체적인 제한: Cron implementations differ; verify field count, day matching, and time-zone policy in the target scheduler.

Cron Generator — FAQ
Does the Cron Generator upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the Cron Generator accept?
It accepts a Unix-style five-field cron expression. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the Cron Generator produce?
It produces a short explanation and the next five scheduled instants. Copy and download controls appear when the output format supports them.
What limitation should I know?
Cron implementations differ; verify field count, day matching, and time-zone policy in the target scheduler.
변경 사항
실질적인 업데이트: Cron Generator: Added Cron validation, Next five runs, IANA time zones, Plain-language summary, responsive controls, explicit runtime disclosure, and task-specific examples and limitations.
