Structured first
Dates, regional scope, holiday types, substitute rules and cultural context are maintained as separate data fields to reduce ambiguity.

About HoliWiki
HoliWiki turns holiday information scattered across government notices, public-holiday systems and cultural traditions into clear, searchable and traceable multilingual data.
Transparent sources
Country calendars link to official sources and state their coverage so readers can verify information against the original notice.
Cross-cultural accuracy
Shared calendars and country-specific traditions are kept distinct instead of merging similarly named holidays into one cultural concept.
Editorial method
How data enters HoliWiki
We prioritize government, public-institution and verifiable calendar sources, then connect holiday dates to encyclopedia definitions. Substitute days and regional scope are identified where possible.
Automation expands coverage, while priority countries and widely viewed holidays receive manual review. Content is continuously revised rather than treated as an unchangeable final record.
