How Minguo years map to Gregorian years

Minguo year 1 began on 1 January 1912. Add 1911 to a positive Minguo year to obtain the Gregorian year; Gregorian 2026 is therefore Minguo 115. This page validates the complete date rather than converting the year alone.

Source and scope

Unicode CLDR identifies the Minguo/ROC calendar as Taiwan’s typical civil alternative calendar, and Unicode LDML defines its era data. Sources checked 29 September 2026.

This tool supports Minguo year 1 onward. It does not guess pre-1912 “before ROC” form conventions. Calculations remain on your device.
