Aargau Public Holidays 2027
Last reviewed: October 14, 2026 · Holiday data: October 8, 2026
The 2027 table for Aargau lists 5 dates: 3 fall on a weekday and 2 on a weekend. That leaves 258 working days in 2027. Like the Switzerland calculator, this page counts Monday to Friday as working days; what changes is the holiday list.
How Aargau differs from the Switzerland calculator
Aargau's law introducing labour law (EG ArR, SAR 961.200, § 6) gives no single list for the canton: it sets the days equal to Sundays district by district, in eight lists. Only Neujahr, Karfreitag, Auffahrt and Weihnacht appear in all of them, and with the Bundesfeiertag on 1 August those five days are what this page counts. Against this site's eight-day Swiss baseline it therefore drops Ostermontag (Easter Monday) and Pfingstmontag (Whit Monday), which the Bremgarten, Laufenburg, Muri and Zurzach districts and six communes of Rheinfelden district do not observe, and Stephanstag (26 December), which Laufenburg, Muri and the same six communes do not observe. It adds nothing. Berchtoldstag (2 January), Fronleichnam (Corpus Christi), Mariä Himmelfahrt (15 August), Allerheiligen (1 November) and Mariä Empfängnis (8 December) are holidays in some districts only; the district table on Aargau's holiday pages for each year shows where each applies. The canton's Amt für Wirtschaft und Arbeit adds that days not listed, 1 May for example, are not statutory holidays in Aargau.

Aargau's holidays district by district, 2027
Section 6 of the EG ArR sets no single list for the canton: it gives each district, and in Baden and Rheinfelden groups of communes, its own list of eight days equal to Sundays, besides 1 August. This page counts only the days every list shares; what follows shows each list in 2027 and what it changes in the count.
The eight § 6 lists in 2027
Each row is one list in § 6 Abs. 1 of the EG ArR. The second column gives the days that list adds to the five that hold across the canton, with their 2027 dates; the third gives the Monday-to-Friday working days left in 2027 under the full list.

Why the lists count differently in 2027
A fixed-date day only costs a working day when it lands on a weekday, so the same list weighs differently from year to year. In 2027, Berchtoldstag (2 January) (Saturday, January 2), Mariä Himmelfahrt (Assumption) (Sunday, August 15), and Stephanstag (26 December) (Sunday, December 26) fall on a weekend and change no count, while Allerheiligen (All Saints' Day) (Monday, November 1) and Mariä Empfängnis (Immaculate Conception) (Wednesday, December 8) fall on a weekday. Ostermontag and Pfingstmontag are always Mondays and Fronleichnam is always a Thursday, so each costs a day in every list that has it. The 2027 result runs from 255 working days (Rest of Baden district (lit. b, 2), Laufenburg and Muri districts (lit. d), Hellikon, Mumpf, Obermumpf, Schupfart, Stein and Wegenstetten, Rheinfelden district (lit. e, 1), and Kaiseraugst, Magden, Möhlin, Olsberg, Rheinfelden, Wallbach, Zeiningen and Zuzgen, Rheinfelden district (lit. e, 2)) to 256 (Aarau, Brugg, Kulm, Lenzburg and Zofingen districts (lit. a), Bergdietikon, Baden district (lit. b, 1), Bremgarten district (lit. c), and Zurzach district (lit. f)), against 258 under the five canton-wide days.
Two examples from this calculator's engine. Fronleichnam falls on Thursday, May 27, 2027: adding five business days to Wednesday, May 26, 2027 lands on Wednesday, June 2, 2027 under the canton-wide set and on Thursday, June 3, 2027 under the list for the rest of Baden district, which has Fronleichnam. Adding one business day to Thursday, March 25, 2027, the day before Karfreitag, lands on Monday, March 29, 2027 under the canton-wide set, which does not count Ostermontag, and on Tuesday, March 30, 2027 under the list for Aarau, Brugg, Kulm, Lenzburg and Zofingen.
The first working day after each holiday, 2027
Computed on Aargau's calendar: a deadline that falls on a holiday and moves to the next working day lands on the date in the third column.
| Holiday | Date | Next working day |
|---|---|---|
| Neujahrstag (New Year's Day) | Friday, January 1 | Monday, January 4 |
| Karfreitag (Good Friday) | Friday, March 26 | Monday, March 29 |
| Auffahrt (Ascension Day) | Thursday, May 6 | Friday, May 7 |
| Bundesfeiertag (Swiss National Day) | Sunday, August 1 | Monday, August 2 |
| Weihnachten (Christmas Day) | Saturday, December 25 | Monday, December 27 |
Aargau working days month by month, 2027
Each month counts Monday to Friday less the holidays that fall on a weekday. The last column is the difference from the Switzerland calculator: in a month with a difference, a deadline counted on the Switzerland calculator can land on another date.
