keskiviikkona

Keskiviikkona is a Finnish time expression meaning "on Wednesday." It is used to indicate a specific day within the week when something happens or is planned to happen. The form is derived from the weekday noun keskiviikko (Wednesday) with a suffix that marks time expressions.

In everyday use, keskiviikkona answers questions of when. For example, you might say, "Tapaaminen on keskiviikkona" (The meeting is on Wednesday). The word can also appear in broader timing contexts, where the exact day is important for scheduling. In addition to keskiviikkona, Finnish also has forms such as keskiviikkoisin to denote a recurring pattern—"on Wednesdays" or "every Wednesday."

Usage notes include that the choice of form can convey whether the timing is a one-off event or a habitual occurrence. The word is part of the standard set of weekday-related phrases and is commonly used in both spoken and written Finnish, including plans, calendars, and announcements.
