Cron Describe

What Cron Describe does

Reads standard cron fields and prints a field-by-field summary. Optional one field per line. Unlike Unix Timestamp this is a schedule, not an epoch. Unlike Regex Tester it does not run a match. Seconds field is optional. Unknown tokens stay as written.

Cron Describe sits in the Developer group on purpose. It is not Unix Timestamp Converter (Unix seconds/millis ↔ date, with timezone display.) and not Regex Tester (Test or replace with a JavaScript regex locally.). Choose this page when you need Explain a 5- or 6-field cron string; optional multiline. If you stretch Cron Describe into a neighbor’s job, the result will look wrong even though the site chrome looks the same.

How to use Cron Describe

1. Keep this tab on Cron Describe (/developer/cron-describe). Pasting into the wrong Developer tool (for example Unix Timestamp Converter) changes the job.
2. Paste or type the input Cron Describe expects. Path hint: developer · cron describe. Explain a 5- or 6-field cron string; optional multiline.
3. Apply the Cron Describe action only. Regex Tester is a different transform (Test or replace with a JavaScript regex locally.). Reads standard cron fields and prints a field-by-field summary. Optional one field per line. Unlike Unix Timestamp this is a schedule, not an epoch. Unlike Regex Tester it does not run a match. Seconds field is optional. Unknown tokens stay as written.
4. Copy the output of Cron Describe if you need it elsewhere. Size/complexity still follows: 5 or 6 whitespace-separated fields. Lists, ranges, stars, and stepped stars. Not a scheduler.
5. If the text job is actually Unix seconds/millis ↔ date, with timezone display., leave Cron Describe and open Unix Timestamp Converter.

When not to use Cron Describe

Skip Cron Describe when a neighbor tool matches better — start with Unix Timestamp Converter or Regex Tester — or when the description already warns the job will fail. In the tool’s own words: Reads standard cron fields and prints a field-by-field summary. Optional one field per line. Unlike Unix Timestamp this is a schedule, not an epoch. Unlike Regex Tester it does not run a match. Seconds field is optional. Unknown tokens stay as written.
