About The Online Calendar.
TheOnlineCalendar is a free, ad-light reference for the world's public holidays — built so that anyone planning travel, business, or time off can find an accurate answer in seconds.
What this site is
TheOnlineCalendar covers public holidays for more than 190 countries across 2026 and 2027, with editorial guides for the world's major religious, civil, and seasonal holidays. Every page is available in ten languages — English, German, Spanish, French, Arabic, Chinese, Hindi, Japanese, Portuguese, and Russian — so the same calendar works for travellers, HR teams, and remote-first companies anywhere on Earth.
Why this site exists
Public holiday data is fragmented. National listings live behind official gazettes, ministry PDFs, and sometimes only in the local language. Aggregators are often outdated, paywalled, or miss substitute days. TheOnlineCalendar exists to be the place where the answer to "is the bank closed on the 4th in Brazil?" is one click away — current, sourced, and free.
What's covered
The calendar includes nationwide public holidays, regional bank holidays where they materially differ, school-term and school-holiday windows for major systems, working-day calculations, long-weekend opportunities, and editorial explainers for festivals such as Eid al-Fitr, Diwali, Lunar New Year, Easter, and Christmas. Where a country observes a substitute day, that's reflected too.
How the data is sourced
Dates are compiled from official government publications: labour ministry circulars, central-bank holiday notices, royal decrees, presidential proclamations, and national gazettes. For Islamic holidays, dates are taken from official moon-sighting committee announcements where available, and clearly marked as estimates where not. Every entry is cross-checked against at least two independent sources before publication, and every country page lists the year of last revision.
Update cadence
The dataset is continuously maintained. When a government issues a new circular, moves a holiday, or adds a one-off observance, the change is reflected on the site within days. New years are added 12 to 18 months ahead of time, with provisional Islamic dates clearly flagged. Changes are documented and the corresponding country page's revision date is updated.
