Automate Terminal-Based Working Day Calculations

The `count_business_days` tool enables Claude Code to quickly calculate working days from your command line. You can pipe the terminal output directly into your cron jobs or deployment scripts to trigger actions based on business days. This allows DevOps engineers to build smart deployment pauses that skip weekends automatically, ensuring production changes only occur during active support hours.

Extract Detailed Date Breakdowns via CLI

The `get_date_breakdown` tool provides Claude Code with a detailed breakdown of years, months, and days directly in the shell. Claude Code uses this to generate uptime reports or calculate the exact age of system logs. Instead of writing complex bash date arithmetic, you let your terminal agent fetch the exact breakdown and format the results instantly for your reports.

Verify Holiday Status in Claude Code Scripts

The `verify_holiday_status` tool lets your terminal agent verify national holidays across different regions. Claude Code checks this status to dynamically adjust automated build schedules or alert rotations. This ensures your on-call rotations and automated tasks adapt to local holiday calendars without manual intervention or hardcoded holiday lists.
