Calendar research and planning

Holiday Planning Guides

Start with the question you need to answer: which date applies, whether a day is officially recognized, what closes, or which calendar format fits your plans. These guides connect that question to the relevant country, category, source, and downloadable calendar.

Choose a Holiday Calendar by Planning Need

Holiday categories are not interchangeable. Use the calendar whose sources and scope match the decision you are making.

Country Holiday Calendar Guides

Open a country calendar when holiday terminology, regional scope, substitute days, or official sources differ by jurisdiction. Each link leads to a full-year calendar rather than a generic global list.

Holiday Date and Status Answers

A date-answer page is useful when the search intent is narrower than a full country calendar. These guides separate the official date from the observed date and explain what a legal holiday status means for planning.

Printable and Downloadable Calendar Guides

Use a yearly PDF for a full-year overview, a monthly PDF when appointments need more writing space, a quarterly calendar for three-month planning, or a country holiday PDF when official dates need to remain visible on the printed page.

Start with the free 2026 PDF calendar library or thefree 2027 PDF calendar library. Selected holiday detail pages also provide single-date ICS downloads for Google Calendar, Apple Calendar, Outlook, and compatible applications.

How to Verify a Holiday Date

  1. Confirm the country, state, province, territory, or regional jurisdiction.
  2. Separate the official holiday date from any observed or substitute weekday.
  3. Use the responsible government or specialist authority for the calendar type.
  4. Check whether a later proclamation, lunar observation, or local notice is still pending.
  5. Verify business, school, bank, market, and postal operations with the organization involved.

A calendar can identify the date and rule, but it cannot guarantee that every private organization will close or that every employee is entitled to paid leave.
