19111990

19111990 is a numeric date string that can denote the date November 19, 1990, depending on regional notation. In ddmmyyyy notation it reads as 19-11-1990, in mmddyyyy as 11-19-1990, and in yyyymmdd as 1990-11-19. The compact form without separators is commonly used in data entry, file naming, and archival systems where fixed-length keys are advantageous. However, the lack of separators can cause ambiguity when the same digits are interpreted under different regional conventions, so explicit formats are preferred in international contexts or standards compliance such as ISO 8601.

The use of 19111990 as an identifier is purely nominal unless anchored to a real event, person, or document associated with that date. In historical timelines, many unrelated events occurred on or around that date, but there is no single universally recognized significance tied to the eight-digit string itself. In computing and information management, sequences like 19111990 may appear as a timestamp, a version tag, or part of a catalog number, often combined with other digits or characters to indicate category, batch, or item.

As a cultural artifact, the arrangement of digits reflects how dates are formatted in particular regions before globalization promoted standardized practices. Related topics include date formats, ISO 8601, and numeric date representations.
