Typical Workflow
When inheriting legacy projects, you often encounter cryptic cron expressions. Paste them into this tool to instantly get human-readable explanations. For example, '30 2 * * 1' becomes 'Runs at 2:30 AM every Monday'. This visual parsing is more efficient than reading raw code.
When setting up CI/CD pipelines, test your expressions here first. For instance, '0 */4 * * *' actually means 'every 4 hours' (not minutes). The tool clearly states 'runs at minute 0 when hour is divisible by 4', preventing scheduling errors before deployment.
Examples
Daily 2am
Input
0 2 * * *
Output
Hour: every hour at 2…
FAQ
6 fields?
Standard 5-field cron only.
Local?
Yes.
Why does */5 mean 'every 5 days' in day field but 'every 5 minutes' in minutes?
This depends on each field's value range. The tool contextually interprets symbols: */5 means 'every 5 minutes' in minutes field (0-59) but 'every 5 days' in day field (1-31). We highlight such potentially confusing operators in yellow for clarity.
