GitHub Scheduler Syntax: Minute, Hour, Day of Month, Month, Day of Week

Each field controls when your GitHub Actions workflow runs. The builder validates your cron expression in real-time, showing you exactly when your automation will trigger. Common patterns: "30 5 * * 1" (Mondays at 05:30), "0 0 * * *" (daily at midnight), "*/30 * * * *" (every 30 minutes).

Export to GitHub Workflows

Once you've built and tested your cron schedule, copy the generated YAML snippet directly into your .github/workflows file. croncrunch handles validation so you avoid silent workflow failures.

Fires once every minute — tightest standard interval.
