Dates

There are several dating schemes:
     -NENGO - Japan's time periods
     -KANSHI - Chinese import, repeating 60 year cycle
     -Years since Imperial ascention JIMMU-TENNO, 660 BC

NENGO are the changing set of common time periods, originally marking the
ascention of a new Emperor. Proclaiming a new time often became 
politically convenient and the occasion of NENGO was expanded. There has 
been several changes of habit regarding the reasoning for changing NENGO.

There has been 232 NENGO from TAI-KA 645, if counting is inclusive to
HEI-SEI 1989. 229 to the MEI-JI 1868. One must remember that the 1st year
of a NENGO is the beginning year, so that adding years to dates must give
one year to that first NENGO year. For instance, SHO-WA is 1926.
Consequently, the third year of SHO-WA is 1928.
NENGO is the most common found date system and is presented for reference 
both alphabetically and chronologically at the back of these books.

      1926 1927 1928 1929 1930 1931 1932 1933 1934

Swords making use of NENGO are carried forth in block form much the same 
as signatures.

See charting in Appendices for all KANSHI and their cross referenced dates.

One will also encounter sword dates of some number of years amounting 
toward 2500 years. 1800 A.D. of the Christian calendar would be 2460 years 
of Imperial rule. These are most likely referencing the reign of 
JIMMU-TENNO.
