    What is Cron Visualizer?

    Useful for sanity-checking crontab entries before deploying them. Supports the standard 5-field format (minute, hour, day-of-month, month, day-of-week) with *, ranges (1-5), lists (1,3,5), and steps (*/15). Month and day-of-week names (JAN, MON) are also accepted.

    FAQ

    Does it support 6-field cron (with seconds)?
    Not yet — only the standard 5-field format. For Quartz-style 6/7-field crons, drop the seconds field first.
    Are times in UTC or local?
    Local time, based on your browser's timezone.
