Cron Expression Parser
Parse and explain cron expressions in plain language when schedules from Airflow, Kubernetes, or legacy cron files need a second opinion. DataEngUtils highlights minute, hour, day-of-month, and day-of-week fields, surfaces off-by-one mistakes, and runs entirely on your Mac so internal job names never hit a public cron calculator. Platform engineers keep it open next to the terminal when onboarding new pipelines or debugging why a DAG did not trigger — especially for expressions copied from Slack that omit timezone context.

How it works
1. Paste a cron string
Enter standard five-field cron syntax such as 0 9 * * 1-5.
2. Read the breakdown
See each field explained and the next few run times when available.
3. Copy a corrected expression
Adjust fields and paste the fixed schedule back into your orchestrator config.
Why not use an online tool?
Online inspectors tools require uploading your pipeline inputs to a third-party server. For production work, that is a security and compliance risk. DataEngUtils runs locally — same convenience, none of the exposure.
