How it works
Enter a standard 5-field cron expression (minute, hour, day-of-month, month, day-of-week). The tool parses each field — handling wildcards (*), specific values, ranges (1-5), step values (*/15), and lists (1,3,5) — and describes the schedule in plain English. It then computes the next 10 upcoming run times starting from the current moment, all in your browser without calling an external API.

Common use cases
- Verifying that a cron job is set to run at the right time before deploying it.
- Debugging an unexpected schedule by reading the human-readable description.
- Quickly generating or checking a cron expression for a CI/CD pipeline.
Frequently asked questions
Does this support 6 or 7 field cron expressions?
No — this tool handles the standard 5-field POSIX cron format (minute, hour, day-of-month, month, day-of-week). Extended formats used by some schedulers (with seconds or year fields) are not supported.
Are all cron shortcuts like @daily supported?
Common shortcuts (@hourly, @daily, @weekly, @monthly, @yearly) are converted to their equivalent 5-field expressions automatically.
What timezone are the next-run times shown in?
Your local browser timezone, which is what most cron jobs run in unless explicitly configured otherwise.
