viikolla

Viikolla is a Finnish inflected form of the noun viikko, meaning week, in the adessive case. It is used to express a time frame within a week or to refer to a specific calendar week, often in scheduling, planning, or reporting contexts. The form is common in calendars, bulletins, and news or public notices that refer to a particular week.

In practice, viikolla is used when stating that something happens during a given week or when identifying the week by number. For example, “Viikolla 23 järjestetään kokouksia ja tapahtumia.” or “Tentti järjestetään viikolla 12.” The expression is also heard in school timetables and project plans to designate time windows, such as “viikolla 9—viikolla 11.”

Relation to other forms: viikolla is the adessive form of viikko. A related form, viikossa, is the inessive form and can carry a slightly different nuance, often translated as “in the week” in contrast to “during the week” in common usage. The choice of form helps specify the intended spatial or temporal perspective within the week.

Etymology and usage notes: Viikko is a native Finnish word for a seven-day period, and viikolla develops from the same root through standard Finnish case endings. In formal or official Finnish, especially in calendars and schedules, viikolla is the expected way to indicate a particular week, especially when a week number is specified.
