About this tool

Cron expressions are compact but hard to read. Paste a standard 5-field cron schedule — minute, hour, day-of-month, month, day-of-week — and get a plain-English description of when it runs. Supports *, steps like */5, ranges like 1-5 and lists. Runs in your browser.

FAQ

In order: minute (0–59), hour (0–23), day of month (1–31), month (1–12), and day of week (0–6, Sunday=0).

Does it support step and range syntax?

Yes — it understands *, */n steps, m-n ranges, and comma lists, and names months and weekdays.

Which cron flavor?

Standard 5-field cron used by crontab, most schedulers and CI systems (not the optional seconds field).
