HolidayCalendar.org started from a simple frustration: holiday information is everywhere, but never in one clear, reliable place.

Public holidays, observances, and special days are often scattered across different websites, calendars, and formats. Getting a clean overview for a specific country or year usually means jumping between sources and reconciling inconsistencies.

HolidayCalendar.org brings these together into a single, structured, and easy-to-browse experience. It covers public holidays, international observances, and thematic calendars, with clean country and year views and individual holiday pages that provide context and related dates.

The focus is on clarity and usability: readable calendars, consistent data, and a simple interface without ads, popups, or distractions. The site is continuously improved by aggregating public sources and normalizing the data for accuracy.

Built for people who need dependable dates, whether for planning, coordination, or curiosity.
