Cron Expression Translator

Cron expressions are time-based scheduling strings with 5 fields: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-6, Sunday=0). Each field can be a value, range, list, or */n for \"every n\". Used in Unix/Linux, CI/CD, and many schedulers.

Reading left to right: minute 0, hour 9, any day-of-month, any month, days 1-5 (Monday-Friday). Translation: \"At 9:00 AM on weekdays.\" Our tool shows plain English for any valid cron expression.

* = any value. , = list separator (1,15 = 1st and 15th). - = range (1-5). / = step (*/15 = every 15). L = last (day of month/week). W = nearest weekday. # = nth day of month (1#3 = first Wednesday).

5-field cron (standard Unix): minute, hour, day, month, weekday. 6-field adds seconds as the first field. 7-field (some systems) adds year at the end. Our tool supports 5 and 6 field formats, the most common.

Enter your cron expression to see the next several scheduled execution times. Verify they match your intentions. Common mistakes: mixing up day-of-month with day-of-week, timezone confusion (cron typically uses server time), and off-by-one errors.
