Cron Expression Builder

Type a standard 5-field cron expression and get an instant plain-English description of when it runs — or start from a preset like "every 5 minutes" or "weekdays at 9am" and tweak it. It removes the guesswork of remembering which field is which.

Use it to sanity-check a crontab entry, a CI schedule, or a scheduled job before deploying it, so you don't discover the timing was wrong in production. Parsed entirely in your browser.
