Their trading hours follow the local time and calendar of each exchange.
Which China Construction Bank stock code should you use?
It depends on the exchange and share class. CCB’s General Shareholder Information FAQ identifies the Hong Kong listing as H-shares on the Hong Kong Stock Exchange (HKEX) Main Board under ticker 939, and the Shanghai listing as A-shares on the Shanghai Stock Exchange (SSE) under ticker 601939. Some quote services display the Hong Kong code as 00939. CCB lists the H-share listing date as 27 October 2005 and the A-share listing date as 25 September 2007. See CCB’s shareholder information FAQ.

Do not confuse the ordinary A-share code with a preference share
CCB’s 2025 half-year report separately identifies a Shanghai-listed domestic preference share under code 360030. That is a different share class, not the ordinary A-share ticker 601939. See CCB’s 2025 half-year report.

How to check whether the market is open on a particular date
Regular hours do not guarantee that trading takes place on a given date. Each exchange has its own holiday calendar and special-session arrangements, so check the intended date on the relevant exchange’s schedule before planning a trade.
