How Business Days Vary by State, Province, and Canton

A "business day" sounds like a fixed unit, the same everywhere inside one country. It is not. Below the national level, a state, province, or canton can add its own public holidays, and in 6 of the 7 countries whose regions this site tracks, it counts those regional days as closures. When they are, they change the arithmetic: the same "ten business days" promise, counted under two different regional calendars, can resolve to two different calendar dates. A deadline is only as precise as the calendar you count it against, and the calendar can change at a state line.

This site tracks 88 sub-national jurisdictions. In 83 of them the regional calendar feeds the business-day count; the other 5 are US states, listed for context. Of the 83, 78 add at least one public holiday their national calendar does not have, and the other 5 differ from it only by national days they do not observe. That is the point of the regional pages: not to restate the national set, but to capture the days that make one region's working year different from its neighbour's. This guide walks through where a sub-national holiday actually moves a deadline, with worked contrasts drawn from the holiday data behind each region page, and it flags the one large exception where state lines do not move the count at all.

A sub-national holiday is a real closure, not a footnote

The site sorts regions into two kinds. In a count-affecting region, the regional public holidays feed the business-day math, because the region's own law makes them closure days. The United Kingdom's nations, the Australian states and territories, the Canadian provinces and territories, the sixteen German Länder, the Spanish comunidades autónomas with Ceuta and Melilla, and the Swiss cantons the site covers all work this way. Select the region and the calculator subtracts that region's holidays, not the generic national set.

The mechanism is a delta. Each region is stored as the national calendar plus the days it adds and minus the days it does not observe. Scotland adds 2 January; Bavaria adds Corpus Christi; Quebec drops the federal Boxing Day date. Every count-affecting region adds a day, drops one, or both, so assuming the national calendar applies builds an error into any count that crosses one of those days.

Germany: the same deadline splits between Munich and Berlin

Germany has nine nationwide Feiertage, and every Land layers its own days on top. Bavaria adds three statewide days to the national nine: Heilige Drei Könige (Epiphany, 6 January), Fronleichnam (Corpus Christi) and Allerheiligen (All Saints, 1 November), for twelve statewide public holidays; Mariä Himmelfahrt (15 August) is a holiday only in its predominantly Catholic municipalities. Berlin adds a single day, Internationaler Frauentag (International Women's Day, 8 March), for ten. So the two calendars diverge on three dates that Berlin works and Bavaria does not, and on one that Bavaria works and Berlin does not.

Watch what that does to a real count. In 2026, Fronleichnam falls on Thursday 4 June, a public holiday across Bavaria but an ordinary working day in Berlin. Count five business days forward from Wednesday 3 June. In Berlin the run is Thursday the 4th, Friday the 5th, then Monday the 8th, Tuesday the 9th, and Wednesday the 10th, so the deadline is Wednesday 10 June. In Bavaria the 4th drops out, so the fifth working day is Thursday 11 June. Same instruction, same starting date, one day apart, because of one Land holiday. The Germany business day calculator uses the national set, while the Bavaria and Berlin pages apply each Land's own calendar.

The United Kingdom: Scotland keeps its own calendar

The United Kingdom does not have one bank-holiday list. Scotland's differs from England and Wales in three standing ways: it adds 2 January and St Andrew's Day (30 November), it takes its summer bank holiday on the first Monday of August rather than the last, and it does not observe Easter Monday. In 2026 it also has a one-off World Cup bank holiday on Monday 15 June. Those differences are spread across the year, so a business-day count that crosses any of them lands on a different date north of the border. A deadline counted through early January is the clearest case, because 2 January is a working day in England but a bank holiday in Scotland.

Northern Ireland works the opposite way. Rather than swapping days, it keeps the full England and Wales set and adds two more: St Patrick's Day (17 March) and the Battle of the Boyne, also called Orangemen's Day (12 July). In 2026 the Boyne holiday falls on a Sunday, and GOV.UK lists Monday 13 July as the bank holiday. The United Kingdom calculator applies the England and Wales set; the Scotland and Northern Ireland pages apply each nation's own bank holidays.

Canada: Quebec stands apart

Canada's provinces diverge widely, and Quebec is the sharpest example. Its statutory calendar adds the Fête nationale du Québec (24 June), a day no other province in the site's data observes, and keeps the Journée nationale des patriotes on the Monday before 25 May, the same Monday on which the federal set has Victoria Day. It does not observe three dates the federal set carries in 2026: the National Day for Truth and Reconciliation (30 September), Remembrance Day (11 November) and Boxing Day, observed on Monday 28 December.

The consequence is concrete. 24 June 2026 is a Wednesday: count five business days from Monday 22 June and the deadline is Tuesday 30 June in Quebec but Monday 29 June in Ontario. The other direction depends on the province, not on Quebec alone. In the site's 2026 provincial calendars, 30 September is a closure in British Columbia, Manitoba, Prince Edward Island and the three territories, and 11 November in nine provinces and territories, while Quebec and Ontario both work those days. This is exactly the situation where "governed by Canadian business days" is not specific enough to settle a date. The Canada calculator applies the federal set, while the Quebec page applies the provincial statutory calendar.

Spain and Switzerland: the comunidad and the canton

Spain fixes its regional holidays through an annual resolution in the Boletín Oficial del Estado, and each comunidad autónoma chooses its own. Andalucía observes the Día de Andalucía on 28 February; Madrid observes the Fiesta de la Comunidad de Madrid on 2 May. In 2026 both fall on a Saturday, so neither moves a count, and the two regions close on the same weekdays that year: Jueves Santo (2 April), 2 November and 7 December, each added on top of the national set. A regional holiday changes a deadline only when it lands on a working day. The Andalucía and Madrid pages each apply their own regional calendar on top of the Spanish national set.

Switzerland shows a wider spread. In the site's data Valais adds five days the national set does not carry: Saint-Joseph (19 March), Fête-Dieu (Corpus Christi), Assomption (Assumption, 15 August), Toussaint (All Saints, 1 November) and Immaculée Conception (8 December). It also drops four days the national set includes: Good Friday, Easter Monday, Whit Monday and 26 December. Zürich adds one, Labour Day (1 May), and drops none. In 2026 that means Valais closes on Thursday 19 March, Thursday 4 June and Tuesday 8 December while Zürich works, and Zürich closes on Good Friday, Easter Monday, 1 May and Whit Monday while Valais works. The Valais and Zürich pages sit either side of the Swiss national calendar.

The exception that proves the rule: US states

The United States is where the pattern stops, and getting this wrong ships a false claim. American states do designate their own holidays. Texas, for example, marks Confederate Heroes Day (19 January), Texas Independence Day (2 March), San Jacinto Day (21 April), and Lyndon B. Johnson Day (27 August). The Texas Comptroller's holiday schedule lists these as skeleton-crew days, on which a state agency must have enough employees on duty to conduct business; of the Texas state holidays, only the Friday after Thanksgiving, 24 December and 26 December close state offices. A federal business-day count follows the federal holidays of 5 U.S.C. 6103, so none of these state days changes it.

That is why this site treats US state holidays as informational only. The US business-day count follows the federal set and does not change from state to state; a deadline of "ten business days" resolves to the same date in Austin as in Boston. The state pages, such as Texas holidays for 2026, list these designated days for context, but they are layered on an unchanged federal count rather than subtracted from it. If a specific court, agency, or contract in one state observes a state holiday for its own deadlines, that is a rule of that forum, not a change to the federal business day, and it should be confirmed against the body that sets it. For the general count, use the United States calculator and read state days as office-closure context.

Getting it right in practice

The fix is the same everywhere the count can move. Identify the jurisdiction that governs the deadline, and if it names a state, province, or canton, count under that region's calendar rather than the national one. When the two sides sit in different regions, agree in writing whose calendar controls, because "business days" alone does not settle it once a regional holiday sits inside the window. Where the count genuinely matters, compute it under the controlling region and share the resulting date, not the formula, so both parties are looking at the same day rather than the same phrase.

For the specifics, the region pages carry each jurisdiction's full holiday set and the official source it was checked against. The countries hub links every national calculator and its regions, the sources register lists the source behind each calendar, and the companion guide on the working week around the world covers the other half of the problem, where the weekend itself sits on different days.

FAQ

Does the same business-day deadline really land on a different date in different states or provinces?

It can, in count-affecting jurisdictions. Across the United Kingdom's nations, the Australian states and territories, the Canadian provinces and territories, the sixteen German Länder, the Spanish comunidades, and the Swiss cantons the site covers, the site counts a regional public holiday as a closure, so a business-day count skips it. Two people counting the same deadline under two different regional calendars reach two different dates whenever a regional holiday falls on a working day inside the window. The United States is the exception: state holidays there do not change the federal count.

Do US state holidays change a business-day count?

No. On this site the United States business-day count follows the federal calendar and does not change from state to state. In Texas, for example, the Comptroller lists Texas Independence Day and San Jacinto Day as skeleton-crew days on which state offices stay staffed. The US state pages list these days for context, but they are layered on an unchanged federal count rather than subtracted from it.

Which German states have the most public holidays?

In the site's 2026 Land calendars, four Länder add three statewide days to the nine nationwide Feiertage: Baden-Württemberg and Bavaria (Epiphany, Corpus Christi and All Saints), Saarland (Corpus Christi, Assumption and All Saints) and Brandenburg (Easter Sunday, Whit Sunday and Reformation Day, the first two of them Sundays). Berlin adds one, Internationaler Frauentag (8 March). In Bavaria, Assumption is also a holiday in predominantly Catholic municipalities. Because Bavaria removes more weekdays than Berlin, a deadline counted in Munich can fall a day later than the same deadline counted in Berlin.

Why does Scotland count business days differently from England?

Scotland's bank-holiday set differs from England and Wales. Scotland adds 2 January and St Andrew's Day (30 November), takes its summer bank holiday on the first Monday of August rather than the last, and does not observe Easter Monday; in 2026 it also has a World Cup bank holiday on 15 June. A business-day count that crosses any of those days resolves to a different date in Scotland than in England. Northern Ireland instead keeps the full England and Wales set and adds St Patrick's Day and the Battle of the Boyne on top.

How do I know which region's calendar applies to my deadline?

Use the jurisdiction named in the contract, statute, or official notice. If it points to a specific state, province, or canton, count under that region's calendar rather than the national one, and confirm which calendar governs in writing when the two sides sit in different regions. The region calculators on this site apply each region's holiday set for you, so you can compute the deadline under the calendar that actually controls it.
