0814

0814 is a four-digit numeric sequence that appears in several contexts, including as a calendar date, a national numbering prefix, a product or catalog identifier, and a computer-data label. In standard decimal notation, the value is 814; the leading zero is typically used to indicate fixed width, an identifier format, or a code rather than a separate numeric value.

Mathematically, 814 is an even composite number. It factors as 2 × 11 × 37. The sum of its digits is 13, so it is not divisible by 3 or 9. In Roman numerals, 814 is written as DCCCXIV.

As a date, 0814 may be read as August 14 in month-day formats. It can also denote the year 814 CE in historical contexts or be used in serial-date stamps as a four-digit timestamp.

In national numbering plans that use long sequences starting with 0, prefixes such as 0814 can designate mobile or landline services. The 08x block is common in some countries, and 0814 appears as a prefix in several of them.

In computing and data-entry, a leading zero can indicate fixed width or an octal literal in some programming languages. For example, in C and C++, a leading zero denotes octal notation, but 0814 is invalid as an octal constant because 8 is not an octal digit.

Beyond numbers, 0814 is used as a model, catalog, or part number in various industries, and can appear in file names, room numbers, or standard forms as a four-digit code.
