How it is calculated

Minguo year 1 is 1912. Minguo year + 1911 = Western year, and Western year − 1911 = Minguo year.
There is no Minguo year 0. 1911 is 1 year before Minguo 1, and N years before Minguo 1 is the year 1912 − N.
The Minguo calendar uses the same months and days as the Western calendar, so only the year changes. For example, 115/10/27 is 27 October 2026.
