Cron for every platform.

Cron expression tools for AWS EventBridge, Kubernetes, GitHub Actions, Spring, Quartz, Jenkins, Azure, GCP, Airflow, and Laravel.

Cron syntax differs across platforms. AWS uses 6 fields with year. GitHub Actions is UTC only with a 5-min minimum. Quartz adds L, W, # special chars. We have a dedicated tool for each.
