19031987

19031987 is a numeric string that can refer to a date or to an identifier in data systems. In contexts that use day-month-year formatting, 19 March 1987 is represented as 19031987. Without separators, however, the digits are ambiguous unless a specific interpretation is defined by a system or convention. Some software expects a delimiter or a fixed order (for example, YYYYMMDD) to parse dates reliably, and a plain eight-digit sequence like 19031987 could be misread if the format is not stated.

Apart from dates, such sequences are sometimes used as codes for records, products, or samples. In archival, library, or inventory metadata, 19031987 might appear as part of an accession number, batch code, or filename, where the digits encode the date of creation or a serial element.

Because date representation varies by region and by software, contexts that employ eight-digit strings should specify the intended format to avoid confusion. See also date formats such as DDMMYYYY, MMDDYYYY, or ISO 8601, which are designed to standardize date representation.
