    What is a CRON expression?

    CRON is a time-based job scheduler in Unix-like computer operating systems. It allows developers to schedule scripts to run automatically. The expression consists of 5 fields that represent the minute, hour, day of the month, month, and day of the week. This visual generator helps you build the correct syntax without having to memorize the specification.
