// about this tool

A cron expression is a compact notation for recurring schedules used in Unix cron jobs, Kubernetes CronJobs, CI/CD pipelines, and task schedulers. This parser translates any expression into plain English and shows the next scheduled run times.

// when to use

Verify a cron schedule before deploying a job
Explain a cron expression to a non-technical teammate
Find the next run time for a scheduled task
Debug why a job runs more or less often than expected

What format does this support?

Standard 5-field POSIX cron (minute hour day-of-month month day-of-week) and extended 6-field format with an optional seconds field at the start.

What does */5 mean?

*/5 means "every 5 units" — in the minute field it means every 5 minutes. The * means "all values" and /5 means "step by 5". So */5 in minutes = 0, 5, 10, 15, ... 55.
