pub type ChineseTraditional = EastAsianTraditional<China>;Expand description
The Chinese variant of the EastAsianTraditional calendar.
This type agrees with the official data published by the Purple Mountain Observatory for the years 1900-2025, as well as with the data published by the Hong Kong Observatory for the years 1901-2100.
For years since 1912, this uses the GB/T 33661-2017 rules.
As accurate computation is computationally expensive, years until
2100 are precomputed, and after that this type regresses to a simplified
calculation. If accuracy beyond 2100 is required, clients
can implement their own [Rules] type containing more precomputed data.
We note that the calendar is inherently uncertain for some future dates.
Before 1912 different rules
were used. This type produces correct data for the years 1900-1912, and
falls back to a simplified calculation before 1900. If accuracy is
required before 1900, clients can implement their own [Rules] type
using data such as from the excellent compilation by Yuk Tung Liu.
The precise behavior of this calendar may change in the future if:
- New ground truth is established by published government sources
- We decide to tweak the simplified calculation
- We decide to expand or reduce the range where we are correctly handling past dates.
