For C.E. dates, the lowercase alphabetic character represents the century. A digit (0-9) is added to represent the decade. If the decade is not known, a hyphen (-) is used instead of a number. A single year or a period within a decade is coded by repeating the appropriate two-character code to create the required four characters.

$b - Formatted 9999 B.C. through C.E. time period
Specific time period formatted as yyyymmddhh, preceded by a code for the era (c for B.C.; d for C.E.).
Era and year are required components; the month, day, and hour are optional.
  • era expressed as a code: c (B.C.), d (C.E.)
  • year expressed as a four-digit number (0000 to 9999) right justified; unused positions contain zeros
  • month expressed as a two-digit number (01 to 12) right justified; unused positions contain zeros
  • day expressed as a two-digit number (01 to 31) right justified; unused positions contain zeros
  • hour expressed as a two-digit number using the 24-hour clock (00 to 23) right justified; unused positions contain zeros
First indicator position values 0-2 specify whether the time period in subfield $b is a single date, multiple dates, or a range of dates. Each 9999 B.C. through C.E. time period associated with the heading is contained in a separate subfield $b.
