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

About HoliWiki
HoliWiki was built around three simple questions: Which countries are celebrating a holiday today? Who gets Christmas off — and on which exact date? And what do holiday arrangements and traditions look like in countries we have never visited? We turned these questions into a structured, multilingual calendar that makes it easy to browse, compare, and understand holidays across the world.
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.
Our story
From scattered notices to structured data
Most holiday tools stop at listing dates. We wanted to answer the questions behind them. The global calendar view lets you pick any day and see every country observing a holiday. A holiday detail page — like Christmas — shows which countries recognize it as a public holiday, on which date, and how observances differ across cultures. Country calendars give the full picture of a nation's annual holiday rhythm, from public holidays to regional observances, each linked to official sources and cultural background.
Our editorial team combines automated data processing with manual review: verifying government announcements, tracking schedule changes, and cross-referencing cultural context. Country coverage expands in phases, with priority given to data quality over quantity. Content is continuously revised — no page is ever final. The goal: to become the world's most convenient and accurate holiday reference. If you share our curiosity about how the world celebrates, we invite you to follow along as we grow.
