Minguo calendar (Taiwan, Republic of China)

The Republic of China (i.e. Taiwan) does not use the same Gregorian calendar used in much of the world: In Taiwan and the rest of the Republic of China, it is not year 2011; it is year 100.

Receipt dated using Minguo calendar: May 3, year 100 of the Republic of China

[For practical purposes, the names Republic of China and Taiwan are used interchangeably, although technically when referring to the entire entity you should say Republic of China, of which Taiwan is more than 99 percent of its territory, the rest being minor outlying islands, including Penghu, Kinmen and Matsu; the Republic of China (i.e. Taiwan) was established in 1911 and is different than the People's Republic of China (i.e. China)].

Following the Wuchang Uprising and Xinhai Revolution of late 1911, and the subsequent collapse of the Qing Dynasty, the Republic of China (ROC) was established on the first of January in 1912, with 1912 then becoming year one of the Minguo calendar. Minguo (民國) translates to English as, The Country of the People. So to determine what year it is in the current ROC era (i.e. on the Minguo calendar) subtract 1911 from the Gregorian calendar: 2011 minus 1911 makes this a monumental year in Taiwanese history.
