The Republic of China (ROC) Calendar

The Republic of China calendar is a solar calendar used in Taiwan and Penghu, as well as by overseas diaspora from those locations. Months and days are identical to the Gregorian calendar, while years are counted with 1912, the year of the establishment of the Republic of China, as year 1 of the ROC/Minguo/民国/民國 era.

The Republic of China calendar should not be confused with the Chinese traditional lunar calendar (see Chinese).

Era codes

This calendar supports two era codes: "roc", corresponding to years in the 民國 (minguo) era (CE year 1912 and after), and "roc-inverse", corresponding to years before the 民國 (minguo) era (CE year 1911 and before).

Month codes

This calendar supports 12 solar month codes ("M01" - "M12")
