Schedule Releases Around Holidays

Deploying software on a public holiday is a recipe for disaster. If something goes wrong, half your team is unavailable to respond. On-call engineers are celebrating with family. Rollbacks are harder when the people who wrote the code are offline. Yet teams accidentally schedule releases on holidays all the time, especially when working across countries with different holiday calendars.

The is_holiday skill lets you check any date against any country's holiday calendar before committing to a release. The holidays skill gives you the full calendar so you can plan release windows months in advance. Together they act as a safety net -- flag every proposed release date against the holiday calendars of every country where you have engineering staff or critical customers.

This matters for DevOps teams, release managers, and engineering leads who set deployment schedules. A two-second check before locking in a release date can prevent a holiday incident that costs the team hours of scrambling and customers hours of downtime.
