# Check International Team Holidays

Distributed teams span time zones and holiday calendars. A Monday that is a normal workday in the US might be a bank holiday in the UK, a national celebration in India, or a religious observance in the Middle East. Missing these differences leads to missed deadlines, empty meetings, and frustrated teammates who expected the day off.

The holidays skill returns the full list of public holidays for any country and year, while is_holiday checks whether a specific date is a holiday in a given country. Together they let you build a complete picture of when your team members are available. Pull holidays for every country where you have employees, overlay them on your project timeline, and identify the weeks where capacity drops.

This is essential for engineering managers, project managers, and anyone coordinating work across borders. Instead of discovering conflicts the week they happen, you plan around them months in advance.
