140518

140518 is a six-digit numeral that may denote a date or serve as a code, depending on context. As a date in formats using two-digit year, month, and day: in YYMMDD, 140518 corresponds to 2014-05-18; in DDMMYY, it would be 14 May 2018. In ISO 8601, the clear form is 2014-05-18. In practice, 140518 also appears in file naming, manufacturing batch codes, or logging as a compact stamp of date; the actual meaning depends on the system's conventions.

Ambiguity can arise when no separators or year century is explicitly stated, particularly in international or cross-system data exchange. To avoid misinterpretation, many systems store dates in a four-digit year format (YYYY-MM-DD) or include a clear delimiter. The interpretation of 140518 thus depends on the regional standard, the industry, and the software or database in use, making explicit formatting important in data transmission.

Beyond dates, 140518 may also function as a production or batch identifier, where the digits encode information such as a production line, lot, or revision number rather than a calendar date. In such uses, the same six digits can carry a purpose distinct from a date stamp, again governed by the issuing organization’s coding scheme.
