About The Online Calendar.
The Online Calendar is a reference site for public holidays and calendar information, covering 190+ countries in 10 languages. We are not affiliated with any government, financial institution, or legal authority.
Our mission
Knowing when public institutions, banks, schools, and businesses are closed is something people need to plan for, regardless of where they live or what language they speak. The Online Calendar exists to make that information accurate, consistent, and freely available.
What we cover
The site covers public holidays for 190+ countries across 2026 and 2027: national holidays, observed dates, and regional variants where the data is available. Alongside the holiday calendars, there are working-day counts by month and year, long-weekend planning guides, and editorial explainers for the major religious, civil, and seasonal observances worldwide.
Our data
Holiday data is sourced from official government publications, national legislative databases, and regional administrative authorities. Every country entry is reviewed at least once a year. Our Data Methodology documents the sourcing process, observance rules, and how corrections are handled. View our Data Methodology →
Our team
Editorial
The Online Calendar Editorial Team
Responsible for the accuracy, tone, and consistency of all published content, including country pages, holiday explainer articles, and regional guides. The Editorial Team applies our Editorial Standards to every piece of content before publication.
Data & verification
The Online Calendar Research Team
Responsible for holiday data sourcing, annual verification cycles, government source monitoring, and correction processing. The Research Team reviews each country's official holiday calendar against primary government sources at least once per year. Their process is documented in full on our Data Methodology page.
Our editorial process
All holiday entries are verified by the Research Team before publication. Changes to holiday dates, names, or observance rules are cross-checked against official sources before being applied. We use AI-assisted tools in parts of our data extraction and content drafting workflow; a human team member reviews all AI-assisted output before it publishes. Our full Editorial Standards cover the correction policy, annual review schedule, and AI-workflow disclosure.
Languages and global coverage
The site publishes in 10 languages: English, French, German, Spanish, Portuguese, Arabic, Russian, Hindi, Japanese, and Chinese. Calendar data, date formats, and regional naming conventions are adapted for each. Editorial content is written in English first.
Report an error
If you find an error in a holiday date, name, or observance rule, please report it. Our Research Team reviews every report, and confirmed corrections are applied promptly. Include the country, year, the incorrect information, and a link to an official source where you can.
