크론 표현식 빌더

A developer tool for building, validating, and previewing cron expressions — no syntax memorization required.

■ Interactive Builder Select values for minute, hour, day, month, and weekday using dropdowns. Build any schedule with a few taps without memorizing cron syntax.

■ Type & Parse Type a cron expression directly and see it instantly translated into plain English. Real-time validation highlights errors immediately.

■ Quick Presets Apply common schedules in one tap: every minute, every hour, daily at midnight, every Monday, first of every month, and more.

■ Next Execution Preview See the next 5 scheduled run times for any expression. Verify your schedule before deploying to production.

■ Expression History Recently used expressions are saved automatically for quick reuse. Swipe to delete individual entries.

■ One-tap Copy Copy any expression to clipboard and paste it directly into your terminal, CI/CD config, or deployment scripts.

Works with Linux crontab, Jenkins, GitHub Actions, AWS EventBridge, Kubernetes CronJob, and any other cron-compatible scheduler.
