Talk:Taika (era)

Visual explanation = simplifying?

This is not simple, but perhaps it can be simplified better?

In the Asuka period after 645 and before Taihō, the Japanese era name system was used only sometimes. This is a bit confusing, but it can be understood with the use of succession boxes — Taika (era), Hakuchi (era), Saimei period, Tenji period, Kōbun period, Temmu period, Shuchō, Jitō period, Mommu period, Taihō (era). Compare NengoCalc which was developed at the University of Tübingen.

After 701, the nengō system was always used, even including the present day. Before 701, nengō were not used during the gap years between Hakuchi and Shuch. Also, nengō were not used in another gap between Shuchō and Taihō.

A. Perhaps there may be ways to improve this set of graphic explanations?

Succession boxes, 645-704

B. Perhaps a modification of Template:WesternSchism will be useful in addition to the succession boxes?

Timelines of early Japanese nengō and Imperial reign dates

C. Perhaps something like the "timeline" graphics created to explain the Nanboku-chō period will be useful for explaining how these years are identified?

Timeline graphics of the Nanboku-chō period
Genealogic tree for the Emperors of Japan, showing the Daikakuji-to and Jimyoin-to branches (in Spanish) Table of the Emperors of the Northern Court and the Southern Court during the Nanobuku-chō period (in Spanish)

Looking forward: Maybe there something about the process of simplifying this pre-Taihō period which might suggest ways to better explain the nengō of the Nanboku-chō period in a visual way? --Ansei (talk) 18:00, 14 November 2012 (UTC)
