About this tool

A cron expression schedules tasks with five fields: minute, hour, day-of-month, month and day-of-week (*/5 * * * * = every 5 minutes). Cron syntax is powerful but cryptic; this generator builds valid expressions from presets and custom fields, and explains what the expression means in plain English. Works for Linux crontab, n8n, GitHub Actions (5-field) and most cloud schedulers.

FAQ

What do the 5 fields mean?

Minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, Sunday=0).

What does */5 mean?

Every 5th value — */5 in minutes = every 5 minutes.

Does it work with 6-field (with seconds)?

Cron parsers differ — remove the seconds field for standard 5-field cron (n8n accepts both).
