In UNIMARC, the code is entered in field 661. The code was developed at the U.S. Library of Congress for use in the USMARC format, now the MARC21 format, and was originally called the Chronological Coverage Code. Code List The Time Period Code consists of four alphanumeric characters assigned according to the tables given below. For B.C. dates, a lowercase alphabetic character represents the millennium and a digit represents the century. If the century is not known, a hyphen '-' is used instead of a number. For A.D. dates, a lowercase alphabetic character represents the century and a digit represents the decade. If the decade is not known, a hyphen is used instead of a number. If a single year or a period within a decade is recorded, the appropriate two-character code is repeated to create the four-character code. B.C. TABLE A.D.

In the A.D. table, the letter equals the century and the number, which must be added, equals the decade.
