Datumlijn

Datumlijn is a Dutch term that literally means “date line” and can refer to several related concepts centered on dates and time in different domains. The most common usage is in journalism, where the term corresponds to the dateline—the line at the top of a news article that identifies the place of reporting and the date of writing. In this sense, the datumlijn serves as a geographical and temporal cue for readers and editors.

In data handling and visualization, datumlijn may describe elements that anchor data in time. It can denote a timestamp field in a dataset, a temporal axis on a chart, or a marker line along a time series that highlights a specific date or event. In user interfaces and data models, naming conventions occasionally refer to a date line or temporal line to emphasize chronological ordering.

The term is also used as a proper name in Dutch-speaking contexts, where Datumlijn may be the name of a company, product, or service related to data management, archival, or analytics. As with many compound Dutch terms, the exact meaning of Datumlijn depends on the domain and context, ranging from publishing practice to data representation.
