Question 1

What is a "red day"?

Accepted Answer

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.

Question 2

Why does Easter move every year?

Accepted Answer

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.

Question 3

Can I focus on one religion?

Accepted Answer

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.

Question 4

Why include Buddhist and Hindu holidays?

Accepted Answer

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.
