cron-builder
Convert natural language to cron expressions and explain complex schedules with run-time projections.

This skill bridges the gap between natural language and complex schedule synchronization. It allows developers to describe timing requirements in plain English and receive precise cron expressions, or conversely, paste cryptic cron strings to get immediate, human-readable explanations. It handles the nuances of different cron syntax variations without requiring external documentation.
Why use this skill
Manually calculating cron schedules is prone to "off-by-one" errors and timezone confusion. Unlike a generic AI prompt, this skill is specifically tuned to recognize cross-platform syntax differences (like Quartz vs. Unix) and provides a structured breakdown including the next five execution times. This ensures your background jobs, GitHub Actions, or Kubernetes CronJobs run exactly when you intend them to.
Supported Formats & Tools
- Standard 5-Field: Unix crontab, GitHub Actions, and Kubernetes.
- Extended 6/7-Field: AWS EventBridge, Spring, Quartz, and node-cron (including seconds and years).
- Special Characters: Supports complex logic using L (Last), W (Weekday), # (Nth weekday), and ? (blank).
- Shorthand Aliases: Handles @daily, @weekly, @hourly, and more.
Use cases
- Generate cron expressions from natural language descriptions
- Translate legacy cron strings into plain English for documentation
- Calculate the next 5 execution timestamps for any schedule
- Verify syntax for GitHub Actions or AWS EventBridge rules
