Great work. Glad to include it. Just one minor request. Please see review.

Hm, I have problems to see any review or minor request. Anyway, this PR will ensure to find the right days of official chinese holidays and those of Hongkong. What is not yet tackled are the complex compensation rules when ever a holiday falls on a weekend (see wikpedia), but this might be realized in another second step (you know better your API). And sometimes the government of China can suddenly change the compensation rules as happened several times in the past, so ultimate safety for any holiday dates is only given by official announcements in December.

I had a quick look at this PR, and trying to understand how the Chinese holidays are arranged. Would the intention for Chinese New Year, for example, be to list holiday as only the actual day, or try to find a way to cover the 7 day holiday from Eve to 6 days later?

I assume would need some additional constructs to calculate this type of requirement.
