19990612

19990612 is a numeric date string in the YYYYMMDD format representing June 12, 1999. In computing and data management, this compact representation is often used because it preserves chronological order when treated as a numeric value and avoids separators that can complicate parsing.

In practical use, 19990612 can appear as a file name, a database key, or a timestamp in logs, and it may be part of a larger identifier or versioning scheme. Such a format is convenient for sorting and indexing large collections of records where the date is a primary attribute. If a time component is needed, systems may extend it with additional digits or a separate time field, for example by appending a time stamp or using an ISO 8601 style date.

Ambiguities can arise if the string is extracted from a context without clear metadata. While 19990612 clearly denotes June 12, 1999 in the YYYYMMDD convention, it does not convey location, time of day, or timezone information. It may also be confused with other regional date formats when converted or displayed in user interfaces.

Related concepts include ISO 8601 representations such as 1999-06-12, and other regional formats like 12/06/1999 or 06/12/1999. When encountering 19990612 in data, additional context is typically required to identify the exact event or record it references.
