Understanding Cron Expressions

Cron is a time-based job scheduler originally from Unix. A cron expression consists of five fields that together define when a task should run: minute, hour, day of month, month, and day of week. Each field can contain specific values, ranges, step values, or wildcards.

This tool parses your cron expression into a human-readable description and calculates the upcoming execution times so you can verify your schedule is correct before deploying it. Common uses include scheduling backups, sending recurring emails, running CI/CD pipelines, and periodic data processing.
