Understand any cron expression — or write one in plain English. Runs 100% in your browser.
Cron is powerful but famously unreadable (0 9 * * 1-5 is gibberish until someone tells you it means "every weekday at 9am"). This tool makes it legible both ways.
Cron → English
- Paste any cron expression → get a clean plain-English description
- See each field broken down (minute, hour, day, month, weekday)
- Next 10 runs computed across 11 timezones (UTC, Europe/Paris, Africa/Tunis, America/New_York, …)
- Supports 5-field (standard), 6-field (with seconds), and 7-field (seconds + year) formats
- Handles lists (
1,3,5), ranges (1-5), steps (*/15),L(last day), and#(nth weekday) - Named values:
MON–SUN,JAN–DEC
English → Cron
- Write what you want in natural language → get the cron expression
- Understands: "every 5 minutes", "daily at midnight", "every weekday at 9am", "every monday at noon", "every 2 hours", and more
