I have heard a couple of people talk about how Chinese holidays can affect importing due to the closing of factories. So here is a pretty good link that list most of the Chinese holidays for 2013, 2014, and future years.
Here is a graph from the website, but I advise going on the website and clicking each holiday to see its actual duration.
I did not see this listed on the forum when I searched for "Chinese Holidays". If something like this is already posted here, then feel free to delete this thread.
