Alkamispäivä

Alkamispäivä is a Finnish noun meaning the day on which something begins or becomes applicable. It is formed from the verb alkaa (to begin) and the word päivä (day). The base form is alkamispäivä, and it is inflected in sentences as alkamispäivän (genitive), alkamispäivänä (inessive), alkamispäivää (partitive), and other cases as required by Finnish grammar.

The term is commonly used in contracts, project schedules, employment terms, education, and event planning to indicate when obligations, rights, or activities start. For example, a contract may state that the alkamispäivä of the agreement is a specific date, or a project timetable may specify the alkamispäivä for the kick-off phase. In everyday usage, the word may appear in phrases discussing when programs or services begin.

Alkamispäivä is related to, but distinct from, related date concepts such as voimaantulopäivä (the date something becomes legally in force) and päättymispäivä (the end date). In many cases the alkamispäivä and voimaantulopäivä coincide, but they can differ when an act or policy starts on a different date from when it becomes enforceable.

Notes on usage and form: alkamispäivää is the partitive singular form used in sentences requiring that case. Finnish speakers may also use synonyms or surrounding phrases such as aloituspäivä or käynnistymispäivä depending on context and style.
