19011988

19011988 is an eight-digit decimal numeral that is often encountered as a date written in the ddmmyyyy format, representing 19 January 1988. In regions using dd-mm-yyyy conventions, it reads as day 19, month 01, year 1988. The fixed eight-digit form is frequently used in computer systems as a compact date stamp or key because it sorts chronologically when treated as a string.

Because date formats vary by region, similar sequences can be interpreted differently if the separators are removed or the order is unknown. ISO 8601 recommends the yyyymmdd format for unambiguous numeric date representations; in that scheme 19880119 would correspond to 19 January 1988, not 19011988. Without separators, the eight-digit string can be ambiguous for some numbers, but 19011988 is most naturally interpreted as ddmmyyyy.

In addition to its use as a date, 19011988 may appear as an identifier or code in datasets, files, or databases that use eight-digit keys based on dates. As a numeric value, 19011988 equals 19,011,988 in decimal and is divisible by 2, illustrating its properties as an even number rather than a prime.

No widely recognized event, person, or organization is universally identified by the eight-digit string alone; its significance is contextual, linked to the date it represents or the system in which it appears. See also date format, ddmmyyyy, and ISO 8601.
