About Red Day Match
Red Day Match is the holiday-recognition game · a public holiday is shown and you match it to its correct date, religion, or country of observance. The game covers Christian, Muslim, Jewish, Hindu, Buddhist, and Secular holidays so a single run takes you across the world's major calendars · the same way an international diplomat or a logistics planner has to keep track of which dates pause business in which countries.
Three round types. Date-match rounds give you a holiday and you pick the correct date (or month, for lunar holidays whose Gregorian date shifts). Religion-match rounds give you a holiday and you pick the tradition it belongs to. Country-match rounds give you a holiday and you pick the country that observes it as a public holiday (often more than one, sometimes just one). The three angles cover the practical questions you'd actually want answered.
Filter by tradition. The default mode mixes all traditions for a polymath drill. Toggle to a single religion · Christian, Muslim, Jewish, Hindu, Buddhist, or Secular only · and the pool narrows to that subset. Useful for focused drilling, or if you're learning about a tradition that isn't your own.
Why holidays are worth knowing. Holidays are the cultural skeletons of the year · they encode what each civilisation chose to mark, mourn, celebrate, or repeat. Knowing them is part of cultural literacy (you can read a Tolstoy novel more easily if you know what Easter Monday is), part of practical international competence (you don't try to schedule a video call during Eid al-Fitr if the other end is in Cairo), and part of self-understanding (knowing where your own calendar comes from). The game is a lightweight way to fill in the gaps.

FAQ
Q: What is a "red day"?
In Scandinavian calendars, public holidays are printed in red · hence the term "red day" (Swedish röd dag, Norwegian rød dag). The game uses it broadly to mean any major religious or secular holiday observed as a public holiday somewhere in the world.
Q: Why does Easter move every year?
Easter is computed from the lunar calendar · the first Sunday after the first full moon on or after the spring equinox · so its Gregorian date slips year-to-year between 22 March and 25 April. The same lunar-anchored logic governs Eid al-Fitr, Diwali, and the Chinese New Year, which is why those dates shift too.
Q: Can I focus on one religion?
Yes · the filter chip switches the pool to just that tradition. The visible holiday count updates so you know how many entries are left to drill. Useful for focused study of one calendar.
Q: Why include Buddhist and Hindu holidays?
Because they are public holidays in significant countries (Thailand, India, Sri Lanka, Nepal, Cambodia, Bhutan, Indonesia, Malaysia, and many others) and they show up routinely in international news, travel planning, and intercultural business. A "world holidays" game that stops at the four Abrahamic traditions misses the calendars of more than two billion people.
