Countries with the most unique holidays

Beyond New Year and Christmas, what does each country celebrate on its own? This ranking measures a calendar's originality: how many of each country's nationwide holidays carry a name almost no one else repeats. Across 40 countries, Japan has the most singular calendar in the sample.

Nearly exclusive nationwide holidays, by country

What makes a calendar belong to one country

Everyone celebrates some New Year, and almost every Christian country stops on Good Friday and Christmas. A calendar's identity lives in the dates almost nobody else has. Here we count, for each country, how many nationwide holidays carry a name that appears in at most two countries of the set. Japan leads with 14 nearly exclusive holidays, followed by South Korea (12) and Argentina (11).

These dates tend to be a country's most interesting ones: independence days, founding battles, local patron saints, civic celebrations that do not travel. The final column shows each country's single most singular holiday, the one unlikely to appear on a neighbor's calendar.
