Aikaväliksi

Aikaväliksi is a translative form of the Finnish noun aikaväli, meaning a time interval. The translative case (-ksi) expresses turning something into or designating it as a particular state or role. In this usage, aikaväliksi means “as a time interval” or “into a time interval.”

Grammatical notes and usage: Aikaväli denotes a span of time between two points, such as a start and end time or date. When a term, dataset, or statement is described as aikaväliksi, it is being defined or assigned as a time interval. This form is common in formal, technical, and scheduling contexts where precision about duration or period is required. The translative contrasts with the inessive or elative forms (for example, aikavälillä meaning “during the time interval” or ajanjaksona meaning “as a period”), which express different relationships to time.

Typical contexts: In planning, reporting, and data analysis, one might define or use a specific period as aikaväliksi, such as “raportin aikaväliksi on määritelty 1.1.–31.12.” or “joukkotiedon aikaväliksi on asetettu 2010–2020.” It is also used in documentation and methodological descriptions to clarify that a parameter or observation is being considered as a time interval.

Related terms: aikaväli (time interval), ajanjakso (period), aikakausi (era). The expression aikaväliksi should not be confused with aikavälillä (during the time interval), which uses a different case form to describe a location in time.
