ABSTRACT:
The present invention provides a new date code with a two digit year code that is compatible with standard date codes, and that may represent dates well beyond the year 1999. The invention defines a set of extended symbols that may be used as first or second digits in the new two digit year code in the new date code. In addition, the invention provides an interpretation of the extended symbols which allows the new year codes to be added, subtracted, or otherwise manipulated and still provide a two symbol representation of years well beyond 1999. In addition, the extended symbols may be used in non-year code mathematical operations to provide an extended range of results that still fit in a two symbol format.
