Typedefs
using	calendar::lunar::algo2::LunarYear
using	calendar::lunar::algo2::LunarMonthChunk
	A chunk of lunar months.

Functions
auto	calendar::lunar::algo2::jde_to_utc8 (const double jde) -> calendar::Datetime
	Convert a JDE (TT) moment to fixed-offset east-eight civil time for lunar date assignment. 把 JDE（TT）时刻转换为固定东八区民用时间，用于确定阴历日期。
auto	calendar::lunar::algo2::calc_lunar_month_chunks (int32_t year) -> std::pair< LunarMonthChunk, LunarMonthChunk >
	Calculate the lunar month chunks for the given year.
auto	calendar::lunar::algo2::leap_month_in_chunk (const LunarMonthChunk &chunk) -> std::optional< int32_t >
	Get the leap month in the given chunk.
auto	calendar::lunar::algo2::calc_lunar_year_start_moment (const LunarMonthChunk &chunk, std::optional< int32_t > leap_month) -> calendar::Datetime
	Get the start moment of the lunar year.
auto	calendar::lunar::algo2::create_lunar_year_context (int32_t year) -> LunarYearContext
	Create a LunarYearContext for the given year, which basically contains the month info, including leap month.
auto	calendar::lunar::algo2::calc_lunar_year (int32_t year) -> LunarYear
	Calculate the lunar year information for the given year. 计算给定年份的阴历年信息。
auto	calendar::lunar::algo2::get_info_for_year (const int32_t year) -> LunarYear
	Get the lunar year information for the given year, using cache. 返回给定年份的阴历年信息。使用缓存。
auto	calendar::lunar::algo2::bounds () -> const common::AlgoBounds &
	The bounds of the algorithm, i.e. the supported range of lunar and Gregorian dates.

Variables
constexpr int32_t	calendar::lunar::algo2::START_YEAR
	The first supported lunar year.
constexpr int32_t	calendar::lunar::algo2::END_YEAR
	The last supported lunar year.
