datumgrens

Datumgrens is a temporal boundary used to determine which data points or events are included in a dataset, report, or analysis. It is a fixed point in time that serves as a cutoff, defining the latest date that is considered for a particular purpose.

In data management, the datumgrens sets the maximum date of data included in a snapshot, study period, or version of a dataset. It helps ensure consistency and reproducibility by preventing changes after that date from affecting the analysis. The datumgrens may be inclusive (data on the exact date are included) or exclusive (data after that date are excluded) and is often aligned with period ends such as month, quarter, or year.

In archival and reporting contexts, the datumgrens delineates the scope of material or results being produced, enabling comparability between datasets and across reports. It can also serve as a deadline for data submission or finalization of a document.

Examples include a sales dataset with a datumgrens of 2023-12-31, including transactions up to that date, or a regulatory report that uses a datumgrens of 31 December 2024 to define the reporting period.

Related concepts include cut-off date, temporal scope, and point-in-time view or snapshot. The exact interpretation of a datumgrens should be documented in project or data governance materials, specifying inclusivity, time zone, and handling of time stamps.
