Houston is 13h behind Shanghai
Houston runs 13 hours behind Shanghai. Houston, United States keeps America/Chicago time (CDT), while Shanghai, China keeps Asia/Shanghai time (GMT+8). When it is 12:00 midday in Houston, the clock in Shanghai reads about 01:00, which is the single most useful number when you are lining up a call. Both cities can move on and off daylight saving time on different dates, so the gap between Houston and Shanghai is not fixed year-round — the live clocks and difference above are recalculated from atomic time sources, so you are always reading the current offset rather than a value that quietly goes stale twice a year.
