Turmeilhais Code

The Turmeilhais Code is a eight-character, alphanumeric code assigned to most characters, on the Turmeilhais database. It consists of three letters and five numbers: the first letter indicates the year of creation. The last digit is the check character using ISO/IEC 7064 MOD 37-2.

Year of creation
Every Turmeilhais Code encodes the year of creation, beginning with 'N' for 1928 (the year the Golden Age of American animation started). Subsequentially, 'O' was for 1940s, 'P' was for 1950s, 1960s, 1970, 1971 and 1972 and 'Q' was for 1973 through 1979 and 1980s with the exception of 1988 and 1989. 'A' was used instead for 1988 and 1989.

The year encoding is as follows:
 * 'N' = 1928, 1929, 1930s
 * 'O' = 1940s
 * 'P' = 1950s, 1960s, 1970 to 1972
 * 'Q' = 1973 to 1987
 * 'A' = 1988 to 1989
 * 'B' = 1990 to 1991
 * 'C' = 1992 to 1993
 * 'D' = 1994 to 1996
 * 'E' = 1997 to 1998
 * 'F' = 1999 to 2000
 * 'G' = 2001 to 2002
 * 'H' = 2003 to 2004
 * 'I' = 2005
 * 'J' = 2006
