A memory media and method of processing date data expressed in a pseudo zoned decimal format The pseudo zoned decimal format differs from the zoned decimal format in that the value of a character contained in the higher order field that corresponds to the F character of the zoned decimal format is permitted to vary in hexidecimal value from 0 to E to represent century information, but is not permitted to have a value of F. This character is examined to detect whether its value is F or a value in the range from 0 to E. If the value is F, the year data is converted to pseudo zoned decimal format in accordance. with century data. If the value is in the range from 0 to E, the value is added to a base century to obtain the proper century.
