This MinguoDate calendar system is primarily used in Taiwan (Republic of China)

 (ISO) 1912-01-01 = 1-01-01 (Minguo ROC) 

To convert the current date to the Minguo date, just subtracts the current year with number 1911, for example

 2016 (ISO) - 1911 = 105 (Minguo ROC) 

1. LocalDate -> MinguoDate

Review a full example to convert a LocalDate to MinguoDate

TestMinguoDate.java

 package com.mkyong.date; import java.time.LocalDate; import java.time.chrono.MinguoDate; public class TestMinguoDate { public static void main(String[] args) { // LocalDate -> MinguoDate System.out.println("Example 1..."); LocalDate localDate = LocalDate.of(1912, 1, 1); MinguoDate minguo = MinguoDate.from(localDate); System.out.println("LocalDate : " + localDate); //1912-01-01 System.out.println("MinguoDate : " + minguo); //1-01-01 // MinguoDate -> LocalDate System.out.println("\nExample 2..."); MinguoDate minguo2 = MinguoDate.of(105, 8, 24); //LocalDate localDate = LocalDate.ofEpochDay(minguo2.toEpochDay()); LocalDate localDate2 = LocalDate.from(minguo2); System.out.println("MinguoDate : " + minguo2); //105-08-24 System.out.println("LocalDate : " + localDate2); //2016-08-24 } } 

Output

 Example 1... LocalDate : 1912-01-01 MinguoDate : Minguo ROC 1-01-01 Example 2... MinguoDate : Minguo ROC 105-08-24 LocalDate : 2016-08-24
