19011987

19011987 is an eight-digit numeral commonly encountered as a date or as an identifier in digital contexts. In the date interpretation, it most naturally reads as 19 January 1987 in the day-month-year format. Without separators or locale context, the same digits can be interpreted differently by software that expects a different date convention.

Applications include file naming, database keys, and other identifiers that require compactness and sortable ordering. Some systems use YYYYMMDD to achieve consistent lexicographic ordering; others use DDMMYYYY or MMDDYYYY, which can lead to misinterpretation of the same sequence across environments.

As a standalone string, 19011987 has no widely recognized cultural or historical significance beyond its numeric value and potential date meaning. It is mainly discussed in the context of date format ambiguity, parsing rules, and data standardization.
