kuupäevavahemikke

A date range, or kuupäevavahemik in Estonian, refers to a period of time specified by a start date and an end date. This concept is fundamental in many areas, including scheduling, data analysis, and historical record-keeping. A date range allows for the precise definition of a duration, encompassing all the days between and including the specified start and end points.

The notation for date ranges can vary. Commonly, it is expressed using a hyphen or a slash to separate the start and end dates, such as "2023-01-01 - 2023-01-31" or "01/01/2023 / 31/01/2023". In some contexts, especially in computing and databases, date ranges might be represented as pairs of date values or through specialized data types that handle temporal intervals.

Understanding date ranges is crucial for tasks like setting deadlines, defining the validity period of a contract or offer, filtering data within a specific time frame, or outlining historical events. For example, when requesting a report of sales, one would typically specify a date range to retrieve data for a particular month, quarter, or year. Similarly, a historical account might refer to a period like "the interwar years," which implicitly defines a date range from the end of World War I to the beginning of World War II.
