@s-molinari Thanks for the reply, the Republic of China calendar(it has another name call “TaiwanCalendar”) is not the lunar calendar(Chinese calendar), it is closer to wareki(Japan calendar).
Only need to change the year display instead .
Not complicated calculations
AD 2020-03-31 same about the ROC calendar 109-03-31 (They’re the same as Tuesday)
Republic of China calendar start about 1912 AD.
The ROC calendar works exactly like the Gregorian calendar, except that the year and era are different.
like…emmmm…this one?C# taiwancalendar
Sorry for that. Maybe I should e.g. wareki .
In Japanese calendar(wareki) 2019AD is call “令和元年”(Reiwa 1st year)
2020AD is call Reiwa 2st year
