我都这样解释:
In Taiwan we have our own calendar and the first year started in 1911.
To convert the year in the taiwanese civil calendar to the Gregorian calendar,
simply add 1911 to the year.
Take myself as an example: I was born in year 82 according to the taiwanese
civil calendar, which means my birth year is 1993 (1911+82) in the Gregorian
calendar.
【词汇解释】
civil calendar: 指一国家内为公民、行政以及官方目的所使用的一种(或其中一种)
历法。
Gregorian calendar: 即全世界广泛通行的西历,由教宗格列哥里13世所创。
