A Developer's Guide to the Cron Job Helper

The Cron Job Helper is a two-in-one tool designed to demystify cron expressions. It helps you validate and understand existing cron schedules, and it uses AI to generate new cron expressions from plain English descriptions.

Validator & Analyzer Features

• Syntax Validation: Instantly checks if your cron expression is structurally valid.
• Human-Readable Description: For a valid expression, the tool uses AI to provide a clear, natural language explanation of the schedule (e.g., "At 09:00 on every day-of-week from Monday through Friday").
• Next Scheduled Runs: See a list of the next 5 upcoming execution times for your cron job, helping you verify that your schedule is correct.

AI Generator Features

• Natural Language Input: Simply describe the schedule you want in plain English (e.g., "every 15 minutes" or "twice a day at 9am and 5pm").
• AI-Powered Conversion: The tool sends your description to a large language model, which translates your intent into a standard, 5-field cron expression.
