The Taiwan calendar works exactly like the Gregorian calendar, except the year is different. Years in Taiwan are calculated from the year 1912, when Dr. Sun Yat-sen founded a republic in China. 1912 represents Year 1 of the Taiwan calendar. To calculate the year in the Taiwan calendar, take the year in the Gregorian calendar and subtract 1911. For instance, the Gregorian calendar year 1971 would be 60 in the Taiwan calendar.
