This topic describes date conversion between Gregorian and Chinese calendars.
The TDateTime class is used to represent the Gregorian calendar date. The class TChineseDate is used to represent the Chinese calendar
date. CChineseCalendarConverter is used for conversion
in either direction between a Gregorian date and a Chinese date.
The CChineseCalendarConverter interface is implemented
by a separate plug-in, which is not provided by this component. If
the plug-in is not available the interface returns an error.
The API consists of two calendar classes: TDateTime and CChineseCalendarConverter, which converts
between TDateTime and TChineseDate formats in both directions. Chinese dates are calculated using the
-2636 epoch. This is equivalent to 2637 BCE (Before Common Era).
