19860519

19860519 is a numeric date string typically used in computing and data recording to denote May 19, 1986. It follows the YYYYMMDD format, with the year first, followed by the two-digit month and day. This compact representation is designed to be both human readable in simple contexts and easily sortable by software.

In ISO 8601, the same date would be written as 1986-05-19. The hyphenated form is preferred in many contexts for readability, but the 19860519 form remains common in filenames, database keys, archival identifiers, and legacy systems where separators are inconvenient or prone to errors.

Practical uses include unambiguous dating in records, versioning, and time-series data where a consistent, zero-padded date field is important. Important to note that 19860519 encodes only a calendar date; it does not specify a time of day or time zone. If a time component is needed, it is typically stored separately.

Historically, the year 1986 included major global events such as the Chernobyl disaster in April and the Space Shuttle Challenger accident in January, which influenced international politics and science policy during that era.

In other calendar systems, the same moment can be expressed differently. For example, in the Japanese calendar, the date 1986-05-19 corresponds to Shōwa 61-05-19.
