Era System (年号 in Chinese or Japanese) is the dating system that is related to an Emperor's crowning. The system began in the Han Dynasty in 1 CE, but it was abolished by the People's Republic of China in 1949, when it adopted the more internationalized Common Era System. The only governments that use that system are Japan and the Republic of China. Wikipedia does not have an article with this exact name. ... A Chinese era name (traditional Chinese: 年號, simplified Chinese: 年号, pinyin nían hào) is the era name, reign period, or regnal title used when traditionally numbering years in an emperors reign and naming certain Chinese rulers (see the conventions). ... 1949 is a common year starting on Saturday. ... The Common Era (CE), also known as the Christian Era and sometimes as the Current Era, is the period beginning with the year 1 onwards. ... The Republic of China (Traditional Chinese: 中華民國; Simplified Chinese: 中华民国; Wade-Giles: Chung-hua Min-kuo, Tongyong Pinyin: JhongHuá MínGuó, Hanyu Pinyin: Zhōnghuá Mínguó, Taiwanese POJ: Tiong-hoâ Bîn-kok) is a multiparty democratic state that is effectively composed of the island groups of Taiwan, the Pescadores, Quemoy...

How it works

When an emperor ascends to the throne, he adopts a throne name (for example, the throne name for Akihito, current Emperor of Japan, is Heisei). From the day that the new emperor ascends to the throne to the end of the calendar year, whether lunar or solar, will be considered the 1st year of his reign (--元年), even though the emperor's 1st year was not a complete year. The year of the emperor continues until a new emperor is crowned.

The Republic of China Era

The Republic of China (ROC) uses the era system even though it does not use a throne name. The Republic of China uses the name "Republic" (民國) for its official dating. The 1st year of the "Republic Era" is in 1912. Therefore, 2004 is "the 93rd year of the Republic Era" (民國93年).

Era System vs Common Era System

While that the era system is a more traditional system of dating that preserves Chinese and Japanese culture, it presents a problem for the more globalized Asian society and for everyday life, too.

For example, even though within the nation people will know what era they are in, it is relatively meaningless for other nations. In addition, while the Government of Japan and the Government of the Republic of China only recognize documents dated in the Era System, their treaties with other countries are in the CE system.

In the domestic arena, the Era system presents difficult dilemmas, too. For example, in Japan, since it is only 16 years into the Heisei Era, it is difficult for others to tell the age of people that are born in the previous era. Also, since the ROC and Japan have adopted the Gregorian calendar, it is difficult to track down the February 29 leap year, more difficult than its internationalized counterparts.

Furthermore, with the exception of the ROC, it is difficult to mention future dates since it is sometimes difficult to tell whether the current emperor will live long enough for its citizens to use that era name.

On the other hand, others suggest that the CE system has too much religious connotation behind it and it is cultural imperialism that a European system is forced upon other civilizations. However, with globalization, there is a trend with Japan and the ROC being more acceptable to the CE system.
