무료 Cron Expression Explainer

사용 방법

Cron expressions like "0 9 * * 1-5" are compact but hard to read. This tool parses the five fields and tells you, in plain English, exactly when the job runs — plus the next few run times.

1. 1
   You type a cron expression

   Standard 5-field cron (or 6-field with seconds), including ranges, lists, steps, month/day names, and @macros like @daily.
2. 2
   Each field is parsed

   The minute, hour, day-of-month, month, and day-of-week fields are expanded into the exact set of values they match — in your browser.
3. 3
   It's explained in English

   The schedule is turned into a readable sentence, with common patterns (weekdays, weekends, "every N minutes") recognised.
4. 4
   Next runs are computed

   The tool simulates the schedule forward to show the next five run times in your local timezone — respecting cron's day-of-month / day-of-week OR rule.
