Cron Expression Generator (AI)
TimeDescribe a schedule in plain English and get back a standard 5-field cron expression, a plain-English recap of when it fires, and a field-by-field breakdown, powered by GPT-4o mini
Describe a schedule the way you'd say it out loud, like "every weekday at 9am" or "at midnight on the first of every month", and GPT-4o mini returns a standard 5-field cron expression along with a plain-English recap and a field-by-field breakdown of what each part means. This is a server-backed AI tool, not a browser-only utility, so the description text is sent to OpenAI's API to generate the response, unlike the purely client-side Cron Parser. It targets standard 5-field cron (minute, hour, day-of-month, month, day-of-week), the format crontab and GitHub Actions both use; if your description is genuinely ambiguous, like "a few times a week", the response includes a warning about the assumption it made. Treat the output as a strong starting point rather than a guarantee: paste the generated expression into the companion Cron Parser or Cron Next Runs tool to confirm it fires exactly when you expect before deploying a schedule change.
