Parse Cron Expressions
Cron expressions define schedules for recurring tasks in Unix/Linux systems, Kubernetes CronJobs, CI/CD pipelines, and cloud schedulers. This tool converts cryptic cron syntax into plain English and shows upcoming execution times.
Cron Format Guide
A cron expression has 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6). Special characters include * (any), , (list), - (range), and / (step). For example, "*/15 * * * *" means "every 15 minutes".
