At Vacanza, we strive to make global holiday data universally accessible and localized for every community and connect the world through data.

Our mission is to create an open, standardized framework that empowers developers and organizations to seamlessly integrate culturally accurate holiday information into their applications. We aim to provide developers and businesses with accurate, localized, and multi-language holiday frameworks that celebrate the diversity of financial markets, countries, and regions.

The Open World Holidays is a framework that provides accurate and reliable public holiday data for 150+ entities around the world. It aims to make this information easily accessible to use in scheduling, planning, and offering localized services (e.g., payroll systems, event planning apps, travel booking websites, or e-commerce platforms that want to offer region-specific services).
