About Calendarific
What is Calendarific?
Calendarific is a RESTful API that provides access to global holiday data, including public, local, bank holidays, and observances. It covers over 230 countries, 3,300+ states, and supports more than 100 languages. Businesses and developers use it to integrate reliable holiday information into their applications, websites, and workflows.
What problem does it solve?
Managing regional holiday calendars manually is error-prone and time-consuming. Calendarific centralizes data from multiple sources, verifies it, and updates it regularly. It eliminates the need for the hassle of maintaining local holiday feeds, so your team can focus on core development. With 10ms latency for 90% of requests, it ensures fast, always-available data.
Who is it for?
Calendarific is ideal for HR platforms that need to sync with employee time-off calendars, e-commerce sites that want to alert customers about shipping delays, and travel or event apps that display local public holidays. It's not suited for those needing data for a single country only; it's designed for global coverage.
Use cases include payroll processing, global team scheduling, billing calendars, marketing campaign timing, and localized content delivery. The free tier is great for startups and developers to test, while premium plans scale to millions of calls.
