tagesgenau

Tagesgenau is a German term describing precision or dating that is tied to the calendar day. It denotes that a datum, calculation, or record is accurate or assigned to a specific date, without specification of the time of day. The word combines Tag (day) and genau (precise) and can function as an adjective or an adverb.

In use, tagesgenau can modify nouns or appear in adverbial form. For example, one might say tagesgenaue Daten or ein tagesgenaues Datum, meaning data or a date that are exact to the day. It can also appear as an adverb: Die Werte werden tagesgenau erfasst, or Die Abrechnung erfolgt tagesgenau zum 31. März. The corresponding noun form is Tagesgenauigkeit, referring to day-level precision.

Fields where the expression is common include finance and accounting (for example, daily or date-specific interest calculations), statistics and data reporting (time series that record values by calendar day), and archives or historical research (documentation with precise date stamps). In these contexts, tagesgenau distinguishes date-level accuracy from finer resolutions such as hourly (stundengenau) or minute-by-minute times.

Limitations and nuances: tagesgenau implies that the relevant temporal unit is the calendar day; if time of day matters, other terms or more specific timestamps are used. The term focuses on date precision rather than the exact clock time, and may be complemented by additional information such as time zones when necessary.
