About the Minguo calendar

The Republic of China calendar is the method of numbering years currently used in the Republic of China (ROC) (Taiwan, Kinmen, and Matsu). It was used in mainland China from 1912 until the founding of the People’s Republic of China in 1949.

Following the Chinese imperial tradition of using the sovereign’s era name and year of reign, official ROC documents use the Republic (literally “The Country of the People”) system of numbering years in which the first year was 1912, the year of the founding of the Republic of China. For example, 2012 is the “101st year of the Republic”. Months and days are numbered according to the Gregorian calendar.

To find out the ROC year equivalent to any Gregorian calendar (CE) year, subtract 1911 from the Gregorian year. For example: 2012 – 1911 = 101st year of the Republic.
