arkipäissä

Arkipäissä is a Finnish linguistic term that refers to the locative plural form of arkipäivä, literally meaning the weekdays. It is formed from arkipäivä (weekday) with the locative plural suffix -issä, yielding arkipäivissä, which denotes “in the weekdays” or “during the weekdays.” The concept is used to indicate time regarded as a category that excludes weekends, often in formal writing, schedules, or normative statements.

In practice, arkipäivissä appears mainly in written or technical contexts, where precise temporal wording is important. In everyday Finnish, speakers more commonly rely on adverbial expressions such as arkisin or arkipäivisin to convey the same idea—“on weekdays” or “during weekdays.” Arkipäivissä thus tends to occur in more formal, legal, administrative, or descriptive prose.

Usage examples include sentences like: “Toimitukset tapahtuvat arkipäivissä” (Deliveries occur during the weekdays) and “Hinnat ovat voimassa arkipäivissä” (Prices are valid during the weekdays). Because it is relatively rare outside formal contexts, arkipäivissä is best understood as a specialized grammatical form rather than a common everyday phrase.

Related terms include arkipäivä (weekday) and the adverbial forms arkisin or arkipäivisin, as well as viikonpäivät for the days of the week. See also: arkipäivä, arkisin, arkipäivisin, viikonpäivät.
