    Introduction

    Cron syntax is compact but cryptic. This explainer turns it into plain English and shows exactly when the job will run next.

    Limitations

    • Covers standard 5-field cron (not Quartz 6/7-field).
    • When both day-of-month and day-of-week are set, cron uses OR logic.

    FAQ
