Cron Expression Builder + Parser

This tool lets you build and inspect multiple cron dialects instead of only plain Unix cron.

How to use:

1. Select a Cron style first. Unix is the default because it is the most common format.
2. Use the Builder form to choose a schedule style like daily, weekly, or every N minutes.
3. Adjust the second, minute, hour, day of month, or day of week values as needed.
4. Click Build Expression to generate the cron string for the selected dialect and preview the next runs.
5. Use the Parser form if you already have a cron expression and want to break down what each field means for that dialect.
6. Supported styles include Unix / Standard, Unix With Seconds, Quartz, and AWS EventBridge / CloudWatch.
