When does the world take a day off?
Two calendars show the days when the most countries, and the most people, are on holiday
In this short post, you’ll see two calendars of national holidays. I created these (interactive) data visualizations because I was curious about the dates of holidays around the world. Keep in mind this data is based on the 2025 Gregorian Calendar, which is used by most countries but not all.
Number of countries with a national holiday
on each day of the month (195 countries, year 2025)
On the other hand…
Number of people observing a national holiday
on each day (195 countries, year 2025)
Overall, three dates dominate: January 1st, Christmas and Labour Day. And then, weighting by population keeps the same top three dates but redraws the rest of the calendar. I assume populous countries like India and China drive most of the other holidays' figures.
