About Calendar & Holidays
The dates other calendars forget — and exactly where they come from.
What this is
ChronoBloom, at calendar-and-holidays.com, is a fast reference for public holidays and cultural festivals across more than 200 countries and territories. The focus is the dates most calendars handle badly: festivals that follow lunisolar calendars — Diwali, Onam, Raksha Bandhan, Bihu, Eid — and land on a different Gregorian date every year.
Where the dates come from
Public holidays are read from open holiday datasets, with a documented fallback chain when one does not cover a country. Cultural festivals come from published calendar feeds spanning 2021–2031, currently across 17 countries. Background descriptions on each festival page are summarised from Wikipedia and link back to the source, which is available under CC BY-SA. Regional tagging — which festivals belong to which part of a country — is editorial, so anything untagged is shown everywhere rather than wrongly hidden.
Dates are shown for reference. Public holiday rules change and lunisolar dates can be revised, so confirm against an official source before making plans that depend on an exact day.
Free festival data API
Each country's cultural festivals are available as same-origin JSON, generated at build time from the source feed. Fetch it with the ISO country code:
GET /api/festivals/<country>.json — for example/api/festivals/IN.json or/api/festivals/MY.json.
Covered countries:IN, US, GB, JP, DE, FR, BR, CN, SG, ID, MY, ZA, AU, CA, PH, VN, KR.
