vuorokautiset

Vuorokautiset is a Finnish term formed from vuorokausi (a 24-hour period) and the adjective-forming suffix -inen; in plural form it is often used to refer to things that occur, operate or are measured over a 24-hour period. The word appears in everyday speech, technical contexts and official language to mark temporality or continuity tied to a single day or a full day-night cycle.

Common uses include descriptions of services that run round-the-clock (for example, vuorokautinen palvelu, a 24-hour service), staffing patterns and work shifts (vuorokautiset työvuorot), and measurements or observations made per day (vuorokautiset mittaukset). In medicine and environmental science the root appears in compounds like vuorokausivaihtelu (diurnal variation) to discuss changes that follow a daily rhythm.

Grammatically, vuorokautinen is an adjective; vuorokautiset is its plural form and can be nominalized to mean “those that are daily/24-hour.” Related Finnish adverbs include vuorokausittain (daily/each 24 hours) and päivittäin (daily). Usage nuances vary by context: in technical writing it often denotes frequency or coverage, while in colloquial use it can simply mean “daily.” The term reflects a focus on the full day as a unit for scheduling, service provision and measurement.
