Switzerland reporting cycles and business-day rules

Swiss business-day cycles align with ESTV (Federal Tax Administration) Mehrwertsteuer (MWST) quarterly returns due by the last day of the month after each quarter-end (Form 0552), and PostFinance / SIX SIS interbank settlement on bank business days. The Swiss National Bank (SNB) holds Monetary Policy Assessments quarterly in March, June, September, and December. SIX Swiss Exchange trades Mon-Fri excluding the federal Swiss National Day (1 August) and Christmas/Boxing Day. Cantonal tax filings vary by canton (typically March 31 for individuals). SwissBanking and FINMA regulate the financial-services sector with quarterly listed-entity disclosure cycles.

Frequently Asked Questions

How many business days are in December 2029 for Swiss federal?
December 2029 has 19 working days under the Swiss federal holiday calendar. The month spans 31 calendar days, of which 10 fall on a weekend and 2 are Swiss federal holidays that lands on a weekday. The remaining 19 weekdays are countable as working days for invoicing, deadline tracking, and contract math.
Which Switzerland holidays affect December 2029?
December 2029 contains 2 Swiss federal holidays: Weihnachten (Christmas Day) on Tuesday, December 25; Stephanstag (Boxing Day) on Wednesday, December 26. Banks and Switzerland financial markets close on each of these days. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
Why is the Swiss calendar federal only, not cantonal?
Switzerland has only three nationally-binding federal public holidays under federal law: New Year's Day (1 January), Swiss National Day (1 August), and Christmas Day (25 December). Each of the 26 cantons (and some major cities) adds its own additional public holidays under cantonal law. This calculator uses the federal three plus the widely-observed Catholic-tradition days (Good Friday, Easter Monday, Ascension, Whit Monday, Boxing Day) that SIX Swiss Exchange and Swiss banks treat as closure days nationwide. Cantonal additions (Berchtoldstag in Zurich/Bern, Allerheiligen in Catholic cantons, the Feast of Geneva in Geneva) are excluded; layer them under Advanced options for cantonal contracts.
How does Switzerland handle weekend-falling holidays?
Swiss federal law does not specify automatic substitute weekdays for weekend-falling public holidays. The Swiss tradition is that holidays absorb into the weekend without an in-lieu Monday. Some cantons (notably in Catholic regions for Allerheiligen) may grant a substitute weekday by cantonal decree but this is not federal. This calculator's data reflects the actual gazetted date; for cross-canton contracts, the federal-plus-widely-observed Catholic set is the conservative baseline. SIX Swiss Exchange and Swiss interbank settlement follow the same observance pattern.
Why does the business-day count vary year to year?
Two things shift the monthly count for Switzerland. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Swiss federal holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. December 2028 also had 19 working days, so the working capacity is unchanged year over year.
