syntymäajan

Syntymäajan is the genitive form of syntymäaika, a Finnish term that refers to a person’s birth date or, in some contexts, birth time. The base word combines syntymä (birth) and aika (time), and syntymäaika is commonly used to describe the date of birth in personal records and official documents. In everyday language, syntymäaika often corresponds to the birth date (day, month, and year), while syntymäpäivä refers more specifically to the birthday celebrated annually.

Usage of syntymäajan appears in civil registries, identity documents, healthcare records, education and employment forms, and other systems that require identifying information. While many day-to-day contexts rely on the birth date in a human-friendly form (for example, 31.12.1990), technical systems typically store birth dates in a standardized format such as ISO 8601 (YYYY-MM-DD). The time of birth is less commonly required and is usually recorded only in medical or genealogical records.

Grammar and forms: syntymäajan is the genitive form of syntymäaika, used to indicate possession or association, for example in phrases like syntymäajan rekisteröinti (registration of birth date) or syntymäajan tiedot (birth date information). The form changes with grammatical context and determiner usage.

Privacy and regulation: birth date is personal data and falls under data protection laws such as the European Union’s GDPR. Its collection and processing are restricted to legitimate purposes (identity verification, legal requirements, age-based access) and should be limited to what is necessary.
