Chinese hour

Also called: chinese hours, double hour, shichen, 時辰

時辰 (shí chen), a double-hour. The Chinese day is cut into twelve two-hour blocks rather than twenty-four single ones, each named for one of the twelve earthly branches and its animal. The first, the Zi hour of the Rat, runs 11pm to 1am — which is why a BaZi day begins at 11pm and not at midnight. Because the blocks follow local clock time, your hour changes when you travel.
