How to use Cron Parser

The cron parser decodes a cron expression and explains it in plain language, while also listing the next run times. Enter the usual five fields (minute, hour, day of month, month, day of week) and the tool tells you when the job will fire. It helps you avoid classic scheduling mistakes, such as confusing the asterisk with a range or misplacing a step value. Everything is parsed in your browser, so your expressions never leave your machine.

Parse a cron expression and preview the next execution times.

Frequently asked questions

Which cron fields are supported?

The five standard fields are supported: minute, hour, day of month, month, and day of week. Common operators such as the asterisk, lists (1,15), ranges (1-5), and steps (*/10) are recognized.

What does */5 mean in a field?

The step */5 fires the job every five units of that field. In the minute field it means the job runs every five minutes.

How do I see the next runs?

The tool calculates and shows the upcoming run times starting from the current moment, so you can confirm the schedule matches what you expect.

Are my expressions stored?

No, parsing happens entirely in the browser. No expression is sent to or kept on a server.
