bundesweite Feiertage in October 2027

No German federal holidays fall on a weekday in October 2027, so the month loses no working day to a holiday on this calendar.

Germany October deadlines

Tag der Deutschen Einheit on 3 October is a gesetzlicher Feiertag in all sixteen Bundesländer, and the Lohnsteuer-Anmeldung for September is due on 10 October. Reformationstag on 31 October is not nationwide: § 30 Abs. 4 StVO lists it for Brandenburg, Bremen, Hamburg, Mecklenburg-Vorpommern, Niedersachsen, Sachsen, Sachsen-Anhalt, Schleswig-Holstein and Thüringen. Sozialversicherungsbeiträge for October fall on the third-to-last Bankarbeitstag under § 23 Abs. 1 SGB IV.

Germany reporting cycles and business-day rules

German business-day cycles run on a few fixed statutory anchors. The Lohnsteuer-Anmeldung is due on the tenth day after each Anmeldungszeitraum under § 41a Abs. 1 EStG, and § 18 Abs. 1 UStG puts the Umsatzsteuer-Voranmeldung on that same tenth day, with the calendar quarter as the default period and the calendar month compulsory once the previous year's tax passed 9,000 euros under § 18 Abs. 2 UStG. Sozialversicherungsbeiträge fall on the third-to-last Bankarbeitstag of the month under § 23 Abs. 1 SGB IV. Einkommensteuer instalments fall on 10 March, 10 June, 10 September and 10 December under § 37 Abs. 1 EStG, and § 31 Abs. 1 KStG carries the same treatment into Körperschaftsteuer. Where any of these lands on a Saturday, Sunday or public holiday, § 108 Abs. 3 AO shifts tax deadlines and § 193 BGB shifts civil-law deadlines to the next Werktag, which is the shift this calculator's Arbeitstage count implements.

October 2027 Arbeitstage compared by country

Working-day counts vary across countries because each country observes its own public holidays. The table below shows October 2027 under 11 of the site's 25 holiday calendars; the summary above gives Germany's own count.

How October 2027 compares year over year

October 2026 had 22 arbeitstage, so October 2027 has 1 fewer working day year over year. On the surrounding months, September 2027 has 22 Arbeitstage and November 2027 has 22. Looking forward, October 2028 has 21 Arbeitstage under the same German federal holiday calendar.

Using this calculator in Germany

A Munich Mittelstand controller uses the 21-day October 2027 count to line up the Lohnsteuer-Anmeldung, due on the tenth day after each Anmeldungszeitraum under § 41a Abs. 1 EStG, with the Sozialversicherung due date on the third-to-last Bankarbeitstag under § 23 Abs. 1 SGB IV. A Hamburg logistics firm counts Arbeitstage to place Skonto windows, where § 271 BGB governs when performance falls due and § 193 BGB moves a deadline landing on a Saturday, Sunday or public holiday to the next Werktag. A Frankfurt finance team uses the same count for the Umsatzsteuer-Voranmeldung, which § 18 Abs. 1 UStG also places on the tenth day after the period ends.

How October 2027 is shaped

The headline count answers how many Arbeitstage October 2027 contains. It does not answer where they sit, and for anything measured in consecutive days rather than cumulative days that second question is the binding one. What follows is derived entirely from the German federal holiday calendar and a working week that treats Samstag and Sonntag as the weekend, with no assumption about how any particular obligation behaves.

A 31-day month opening the final quarter

October runs 31 days and opens Q4, the last quarter of the calendar year, so everything deferred earlier arrives inside a period that begins here. It shares its weekday alignment with January in a common year. As a 31-day month it carries three weekdays five times, and which three is decided entirely by the day it opens on.

In October 2027 that comes to 21 Arbeitstage across 31 calendar days, against 22 in September 2027 and 22 in November 2027.

The month opens on the last day of a working week

October 2027 starts on the final working day of a week. One working day stands between the 1st and the weekend, so the month's real momentum does not begin until the following week. This is the start that most compresses a monthly plan: the calendar has turned, but only one working day has passed before the first closure.

The month's first working day is Friday, October 1, and October 2027 carries 21 Arbeitstage in total.

Five working stretches

October splits into five working stretches. That is the ordinary shape of a month whose only interruptions are its weekends, and it means the month's internal boundaries are all predictable a year in advance: nothing here depends on a holiday date moving.

The working days of October 2027 arrive in stretches of 1, 5, 5, 5, and 5 days. The longest unbroken stretch runs five days, from October 4 to October 8. A task needing more consecutive Arbeitstage than that cannot be completed inside a single stretch, whatever the month's total looks like.

The month is back-loaded. It opens with one consecutive day and closes with five, so the room is at the end rather than the start. That is the safer of the two imbalances, because a slip has somewhere to go, but it also makes the opening week a poor sample of the month.

Three weekdays occur five times

A 31-day month contains four full seven-day cycles and three days over, so exactly three weekdays occur five times and the other four occur four times. In October 2027 the three are Sunday, Friday, and Saturday. Which three it is follows entirely from the weekday the month opens on, which is why the working-day count of a 31-day month moves year to year even when its holidays do not.

Only Friday among them is a working day, so part of the surplus is absorbed by the Samstag and Sonntag weekend and never reaches the working total. That split is why two months of the same length can carry different working-day counts without any holiday being involved.

Every holiday this month falls on the weekend

October 2027 does contain a German federal holiday, but it lands on the weekend (Samstag and Sonntag under this calendar): Tag der Deutschen Einheit on Sunday, October 3. A holiday costs a working day only when it displaces one, so a weekend-falling holiday leaves the month's count untouched.

Whether the day off is recovered on an adjacent weekday depends on the substitution rule of the jurisdiction, which varies and is not assumed here. This calculator counts only the dates its holiday data publishes, and for October 2027 that data lists no German federal closure on a working day. Where a substitute weekday is granted, the data set carries it as a separate entry with its own date.

A long stretch with no closure at all

October 2027 sits inside an unusually long run without a German federal closure. Neither the month itself nor either edge of it carries one within a month, which means the working-day count here is set by the weekend pattern alone and will repeat exactly in any year with the same alignment.

Looking outside the month, the last was Pfingstmontag on May 17, 2027, 137 calendar days before October began and the next is Karfreitag on April 14, 2028, 166 calendar days after it ends.

Across the whole of 2027 the German federal calendar puts five closures on working days, of which none falls in October. That ratio, rather than the raw count, is what tells you whether a month is carrying more than its share of the year's downtime.

The month ends over a weekend

October 2027 ends on a Sunday, which this calendar treats as weekend. Month-end processing cannot happen on the last calendar day, so it happens earlier and the last few dates of the month carry no settlement at all. The distance between the final working day and the final calendar day is where month-end reconciliations go missing.

The last working day of October 2027 is Friday, October 29. Counting back from there, the third-to-last is Wednesday, October 27, four calendar days before the month closes.

The working month ends on the last working day of a week, so the final stretch is a complete one and nothing is left hanging mid-week. Two calendar days of October follow it with nothing settling on them.

The quarter opens here

October is the first month of Q4. An opening month sets the baseline the rest of the quarter is measured against, and it is the one month where a slip has two further months to be absorbed in. Quarterly targets divided evenly by three ignore the fact that the three months rarely carry equal working-day counts.

Across the whole quarter there are 66 Arbeitstage, of which 21 fall in October. The other two months carry November 2027 with 22 and December 2027 with 23. It is the smallest of the three, so the quarter's capacity sits mostly in the other two months and a plan that spreads work evenly across the quarter will over-commit October.

The week's first working day is the scarcest

The first working day of the week is the one October gives least often. Anything anchored to the start of the working week (a weekly kickoff, a Monday-morning cutoff, a start-of-week batch) fires fewer times this month than the calendar count suggests, because a closure has taken one of them out.

Counted as worked rather than as occurring, October 2027 gives Monday 4, Tuesday 4, Wednesday 4, Thursday 4, and Friday 5. A weekly commitment pinned to a particular weekday fires that many times in the month, which is the number a rota needs and not the one the calendar shows.

Toward the short end of the year

October sits among the shorter working months of 2027 under the German federal calendar. A month reaches this end of the ranking either by being short or by absorbing closures, and the two produce the same headline number while behaving differently: a closure fragments the month, a shorter calendar does not.

2027 carries 256 Arbeitstage in total under the German federal calendar. The longest month of the year is December 2027 with 23 and the shortest is May 2027 with 19, a spread of 4. October ranks 9th of the twelve with 21.

Germany closures across the year

A month's working-day count only means something against the country's whole calendar. Two countries that share a weekend and happen to have the same closure-free month can still run very different years, and Germany is placed as follows.

Across 2027 the German federal closures fall 3 in Q1, 2 in Q2, 0 in Q3, and 0 in Q4. A further four holidays land on the Samstag and Sonntag weekend and cost no working day at all, which is why a country's holiday count and its working-day loss are different numbers.

The longest uninterrupted run in the 2027 calendar sits between January 1, 2027 and March 26, 2027, 84 calendar days with no German federal closure in between. Stretches like that are where multi-week work belongs, and they move from year to year whenever a movable holiday does.

After the year's last closure

October 2027 falls after the last German federal closure of the year, so nothing further in 2027 reduces a working-day count. Where a deadline runs from this month into the next year, the closures that can move it all belong to the following year's calendar rather than this one.

2027 opens its German federal closures with Neujahrstag on January 1, 2027 and ends them with Pfingstmontag on May 17, 2027. The densest month of the year is March 2027 with two closures on working days.

One working day fewer than last year

October 2027 has one Arbeitstage fewer than October 2026: 21 against 22. On a monthly target that is roughly 5% less working time for the same calendar period, which is the size of gap that shows up as an unexplained miss rather than as a known constraint.

October opens 2026 on a Thursday, 2027 on a Friday, and 2028 on a Sunday. That movement, one weekday in a common year and two after a leap day, is what makes the three counts differ. The number of closures on working days is the same in both years, so the whole of any difference comes from weekday alignment. Looking ahead, October 2028 carries 21 Arbeitstage.

Where the month's anchor dates fall

Two of the common monthly anchor dates in October 2027 land outside the working week or on a closure. The table below resolves each one against the German federal calendar, together with the first working day on or after it.

The final column is arithmetic, not a legal conclusion. Whether an obligation actually moves when its date is not a working day depends on the instrument that sets it, and this site does not assume a shift rule for any jurisdiction. Where a rule is known it is stated in the holiday data methodology and on the country page it applies to.

Net terms dated in October 2027

An invoice dated the 1st of October on calendar-day Net 30 terms comes due on October 31, 2027, which is not a working day under the German federal calendar. A term counted in calendar days can land anywhere in the week, and roughly two days in seven it lands somewhere nothing settles, which is the ordinary reason a payment shows as late by a day or two without anyone being late.

Net 30 and Net 60 are commercial conventions rather than statutory periods, and both are counted here in calendar days, which is how they are almost always written. Where a contract counts in working days instead, use the between-dates calculator with the Germany calendar selected, because the two produce different dates whenever a closure falls inside the term.

Frequently Asked Questions

How many business days are in October 2027 under the German federal holiday calendar?
October 2027 has 21 Arbeitstage under the German federal holiday calendar. The month spans 31 calendar days, of which 10 fall on a weekend and 0 are German federal holidays that land on a weekday. The remaining 21 weekdays are countable as Arbeitstage for invoicing, deadline tracking, and contract math.
Which Germany holidays affect October 2027?
October 2027 contains no German federal holidays that fall on a weekday, so on this calculator's holiday set the month loses no working day.
Why does this calendar use only the nationwide holidays?
Tag der Deutschen Einheit on 3 October is a statutory holiday by federal law (Einigungsvertrag, Art. 2(2)); the other holidays are set by the Länder, each in its own Feiertagsgesetz. The nine bundesweite Feiertage in this calculator are the days every Land observes: Neujahrstag, Karfreitag, Ostermontag, Tag der Arbeit, Christi Himmelfahrt, Pfingstmontag, Tag der Deutschen Einheit, Erster Weihnachtstag and Zweiter Weihnachtstag. Days that only some Länder observe are not included: Bavaria, for example, adds Heilige Drei Könige, Fronleichnam and Allerheiligen statewide and Mariä Himmelfahrt in municipalities with a predominantly Catholic population, Berlin adds the Frauentag on 8 March, and Saxony adds Buß- und Bettag.
How does § 193 BGB shift deadlines that land on a Feiertag?
§ 193 BGB applies where a declaration is to be made or a performance rendered on a set day or within a period: if that day, or the last day of the period, is a Sunday, a public holiday recognised at the place of declaration or performance, or a Saturday (Sonnabend), the next Werktag takes its place. The tax code has a parallel rule for tax periods in § 108 Abs. 3 AO. A ten-day payment period whose last day is Karfreitag therefore runs past Ostermontag to the Tuesday. This calculator does not apply the shift itself: in calendar-day mode its result can fall on any day, and in business-day mode never on a weekend or a holiday.
Why does the business-day count vary year to year?
Two things shift the monthly count for Germany. First, the day of the week the first of the month lands on changes the count of each weekday. Second, German 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. October 2026 had 22 arbeitstage, so October 2027 has 1 fewer working day year over year.
When is the last working day of October 2027?
The last working day of October 2027 under the German federal calendar is Friday, October 29. The month's last calendar day is Sunday, October 31, which is not a working day, so month-end processing has to happen two calendar days earlier than the calendar suggests. Counting back, the third-to-last working day is Wednesday, October 27.
How many working days in a row does October 2027 offer?
October 2027 has 21 Arbeitstage in total, but they do not run consecutively. They arrive in five stretches of 1, 5, 5, 5, and 5 days, so the longest unbroken run is five days, from October 4 to October 8. No working day in the month is isolated between two closures.
