0029

0029 is a four-digit string consisting of two leading zeros followed by the digits 2 and 9. As a numeric value it represents 29 when leading zeros are ignored. In many systems, 0029 is used as a padded identifier to fixed width fields, ensuring uniform length for sorting or alignment.

When interpreted as a year, 0029 commonly denotes the year 29 CE in the Anno Domini era. In historical dating, the exact calendar system can vary (Julian or proleptic Gregorian) and depending on scholarly convention, events attributed to year 29 might be listed differently.

Computing and data formatting: In programming, literals with leading zeros can have special meaning in some languages, such as octal notation in older languages, though modern languages often treat leading-zero numbers as decimal or require explicit string handling. Because of potential ambiguity, 0029 is frequently stored and transmitted as a string to preserve the padding.

Applications: The sequence appears in product codes, model numbers, invoice numbers, or library or archive identifiers. It can function as an index within larger catalogs or classification schemes.
