Public holidays and calendars

Public holidays are not universal. Their dates, frequency, and legal force depend on national law, regional practice, and the shifting positions of lunar or religious calendars. To compare countries reliably, you must distinguish three layers: nationally fixed public holidays (set by statute or decree), regionally observed days (varying within a country), and movable dates that change each year. The following method gives you a consistent decision rule for any country comparison.

Identify the national legal framework

Every sovereign state publishes its official public holidays in a government gazette, labor code, or decree. The source is always the national government, typically the ministry of interior or labor. For example, Germany’s public holidays are set by the states (Länder) under federal framework law, while Japan’s are listed in the National Holiday Law (Shukujitsu-hō), last amended in 2023. You must verify the current list from the official gazette of the country in question, because laws change. As of 2024, the number of nationally mandated public holidays ranges from 8 (e.g., Canada) to over 20 (e.g., Cambodia, Sri Lanka), according to national statistical offices.

Decision rule: When comparing two countries, first check whether each holiday is established by national law, regional law, or collective agreement. If you need a single count, use the national statutory minimum. Note that countries with federal systems (United States, India, Australia) have state-level holidays that do not appear in a national list.

Distinguish fixed from movable holidays

Fixed holidays occur on the same calendar date every year. Examples: New Year’s Day (1 January), Bastille Day (14 July in France), Independence Day (15 August in India). Movable holidays shift according to a lunar or religious calendar and must be calculated annually.

Easter is the most common movable holiday in Christian-majority countries. Western churches define it as the first Sunday after the first full moon on or after 21 March (astronomical calculation, source: astronomical convention, annual). Eastern Orthodox churches use the Julian calendar, so Easter often falls one to five weeks later. Lunar calendar holidays include Chinese New Year (second new moon after the winter solstice, between 21 January and 20 February), Diwali (the 15th day of Kartika in the Hindu lunisolar calendar, between mid-October and mid-November), and Ramadan-related holidays (Eid al-Fitr and Eid al-Adha, based on the Islamic lunar calendar, advancing about 11 days each year). Decision rule: For any movable holiday, note the calculation method (astronomical or religious authority) and the reference year. Never assume a movable date from a previous year is correct for the current year.

Understand regional and local variation

Many countries have holidays that apply only in certain regions, states, or provinces. For example, in Switzerland, public holidays are set by each canton; the federal level designates only a few national days (e.g., Swiss National Day, 1 August). In Spain, each autonomous community observes its own regional day alongside national holidays. In India, each state declares its own list of holidays under the Negotiable Instruments Act, 1881, and the list changes annually.

Decision rule: When comparing countries, specify whether you are looking at the national minimum or a particular region. If the source does not state the region, assume the national statutory level. For travelers or researchers, always consult the official list of the specific region or city.

Weekend definitions differ

The standard weekend in most countries is Saturday and Sunday. However, several countries use a different weekly rest period. As of 2025, the IANA timezone database records the following patterns: Israel (Friday, Saturday); Saudi Arabia (Friday, Saturday); Iran (Thursday, Friday); Brunei (Friday, Sunday); and some jurisdictions (e.g., parts of Nepal) observe Saturday only. Decision rule: When counting public holidays, check whether a holiday that falls on a weekend is replaced by a weekday off (a “bridge day” or “in lieu” day). This practice varies by country and by year. For example, in the United Kingdom, if Christmas Day falls on a weekend, the following Monday is substituted; in Japan, the substitute holiday law (National Holiday Law, Article 3) provides a replacement weekday.

International days and UN recognition

The United Nations designates 193 international days (UN General Assembly resolutions, 2025). These include World Health Day (7 April) and United Nations Day (24 October). These are not public holidays unless a national government enacts them as such. Many countries do not observe any UN-designated days as public holidays. Decision rule: Do not assume a UN international day is a public holiday in any given country. Always verify against national law.

School holiday periods

School holidays are set by national or regional education ministries and follow the academic year, which varies by hemisphere. In the northern hemisphere, summer break typically falls in July, August; in the southern hemisphere (e.g., Australia, Chile), summer break is December, February. School holidays are not public holidays in the legal sense, but they affect travel and business operations. Decision rule: When comparing countries for travel or business planning, distinguish public holidays (legally mandated days off) from school holidays (regulated by education authorities). The two lists rarely overlap completely.

Practical checklist for comparing public holidays

To compare public holidays for any two or more countries, follow these steps:

1. Obtain the official list from each country’s national government gazette or labor ministry website. Use the most recent annual publication (source: national government gazette, annual).
2. Identify fixed vs movable. Mark each holiday as fixed (same date each year) or movable (requires annual calculation). For movable holidays, note the calculation rule.
3. Note the weekend definition. Check the IANA timezone database (2025) for the country’s weekly rest pattern.
4. Check for substitute days. Determine whether a holiday falling on a weekend is replaced by a weekday off. This is usually stated in the same law.
5. Count only national statutory holidays for a baseline comparison. Add regional holidays only if the comparison is region-specific.
6. Verify the year. Public holiday lists change. A list from 2020 may be invalid by 2025. Always cite the year of the source.
7. Do not assume religious holidays are universal. For example, Eid al-Adha is a public holiday in Indonesia (2024) but not in Japan. Verify each country’s official inclusion.

Common pitfalls

• Assuming a single number tells the whole story. The number of public holidays says nothing about their cultural importance or economic impact. Two countries with 12 holidays may have entirely different distributions across the year.
• Mixing fixed and movable without adjustment. A count that includes Easter and Chinese New Year as single dates is misleading, they shift annually.
• Ignoring regional variation. A national count omits state-level holidays in federal countries, which can add 5-10 days in some regions.
• Using outdated sources. A 2019 list for Venezuela, for example, may not reflect subsequent decree changes.
