aikakehyksiin

Aikakehyksiin is the illative plural form of aikakehys, a Finnish term describing the temporal boundaries used to delimit the scope of an analysis, report, or plan. An aikakehys defines what time period is being considered and what events or data should be included or excluded. The concept is widely used in research, journalism, policymaking, and project management to create a coherent temporal context.

The term derives from aika (time) and kehys (frame). The illative plural form aikakehyksiin is used when referring to several time frames into which material is organized or allocated, as in “aineisto jaettiin kahteen aikakehykseen” (the data were divided into two timeframes).

Use in practice:

- In research, researchers specify aikakehyksiin to set observation windows, projection horizons, or comparative periods.

- In journalism and media, aikakehyksiä help to place events within specific periods to facilitate narrative coherence.

- In policy and planning, they guide targets, milestones, and evaluation points.

- In historical analysis, multiple aikakehyksiin allow side-by-side comparisons of different eras.

Relation to other terms:

Aikakehys contrasts with related concepts such as aikajakso (time span), aikaväli (time interval), aikajänne (temporal span), and aikakausi (era). While aikakehys provides the boundary, the other terms describe the duration, segmentation, or cultural-historical context within or across those boundaries.
