Abstract:

The method for encoding a date for universal recognition provides a representation of a date that eliminates ambiguities that may arise because of different date formats widely used throughout the world. A date is encoded by first expressing the date as at least a calendar month and a calendar year within a calendar system. A month identifier is encoded for the calendar month. The month identifier comprises a first identifier field having a first association with the name of the month, and a second identifier field having a second association with the name of the month. Next, a year identifier is formed for the calendar year. A date representation is formed by formatting the month identifier together with the year identifier. Visual indicia of the date representation are formed on an article to express a date of interest, such as an expiration date on a credit card.
