Whether you're a teacher building a lesson plan, a student researching a holiday, or just curious — here's what people ask most.
Dates To Know is a free, ad-free atlas of holidays, festivals, awareness days, and cultural observances from every country in the world. It's built for teachers planning multicultural lessons, students researching for school projects, HR professionals scheduling fairly across global teams, travelers planning trips around festivals, and anyone curious about how humans mark time.
Every entry includes a brief history, the date, the type of observance, and links to authoritative resources for further reading.
Fixed-date holidays — like Bastille Day on July 14, or Christmas Day on December 25 — repeat on the same date every year and are accurate as listed.
Movable feasts — like Easter, Eid al-Fitr, Diwali, Lunar New Year, Yom Kippur, and any holiday observed on "the second Sunday of" a month — shift by year and sometimes by region. The dates shown reflect the 2026 occurrence. For travel, school events, or any official scheduling, always verify with a local source closer to the date.
For most academic purposes, citing the primary source is stronger than citing Dates To Know itself. Each entry's "Resources for Research" links lead directly to authoritative sources — UN agencies, UNESCO, WHO, government archives, the Library of Congress, peer-reviewed encyclopedias, and major patient or advocacy organizations. Use those.
Dates To Know works best as a starting point for discovery: find the holiday here, then follow the linked sources for material you can cite directly. Always double-check dates and details against multiple sources for academic work.
Public Holiday — a day when banks, schools, and government offices typically close (e.g. Labor Day, Independence Day).
Religious — observed by a faith tradition with associated rituals or fasting (e.g. Ramadan, Diwali, Easter).
Cultural Festival — celebrations of identity, heritage, harvest, or the arts (e.g. Mardi Gras, Holi, Pride Month).
National Day — commemorates a country's founding, independence, or a defining historical event.
Observance — a day to commemorate, honor, or celebrate (e.g. Mother's Day, International Day of Peace, Holocaust Remembrance Day).
Awareness Day — a day specifically focused on raising awareness of a health condition, social cause, or community (e.g. World Autism Awareness Day, World Cancer Day, Disability Pride Month).
After applying any filters or search terms, scroll to the toolbar above the cards. You'll see three download buttons:
↓ CSV — opens in Excel, Google Sheets, or Numbers. Best for sorting, sharing as a spreadsheet, or importing into another tool.
↓ JSON — for developers and technical users. Includes structured metadata about your filters and the export.
⎙ Print — generates a clean printable layout of just the results, with all the cards and no nav, headers, or footer clutter.
The download reflects whatever filters you currently have active — so you can grab "all March observances" or "every awareness day in a single CSV" with two clicks.
Holidays are deeply local. Many regions, religions, and communities have their own calendars and observances that don't appear on global lists. We've worked to be comprehensive — over 440 entries covering every continent — but no atlas is exhaustive.
Date discrepancies usually come from one of three sources: movable feasts (Easter and Eid shift each year), regional variation (some countries observe a holiday on a different date than the canonical one), or Gregorian-vs-traditional-calendar differences (Orthodox Christmas, Coptic Easter, Hijri Islamic dates, the Hebrew calendar, and the Chinese lunar calendar all map differently to the Gregorian system).
Dates To Know includes comprehensive coverage of disability awareness days, weeks, and months — drawing on community-led sources like the Autistic Self Advocacy Network, the Disability Visibility Project, Mencap, the Amputee Coalition, and the Microassist disability awareness calendar.
Throughout, we follow the language preferences of each community: identity-first language where the community prefers it (e.g. "Autistic Pride Day"), centering self-advocates over caretakers, and using "Acceptance" framing over "Awareness" where the community has called for that shift.
The site itself is built for accessibility: keyboard navigable, screen-reader friendly, with focus indicators on every interactive element, and color contrast meeting WCAG standards.
Entries marked "Worldwide" are observed across many countries — typically days proclaimed by the United Nations, WHO, UNESCO, or other global bodies (like World Health Day or International Women's Day), or religious feasts shared across the worldwide community of a faith (like Easter or Eid al-Fitr).
Country-specific entries are tied to a particular nation's calendar, history, or culture (like Bastille Day in France, Diwali in India, or Día de los Muertos in Mexico) — even when those holidays are also celebrated by diaspora communities elsewhere.
Dates To Know is updated periodically as new observances are formally established, dates shift, or community feedback identifies missing entries. The dataset is curated rather than auto-generated — every entry has been hand-researched and written for accuracy and respectful framing.
