No, Chengdu and Beijing do not have different time zones; both cities, along with the rest of mainland China, operate on China Standard Time, which is UTC+8 year-round. Since China does not observe daylight saving time, there is no seasonal change in the time difference between the two cities. Although Chengdu is located significantly further west than Beijing, meaning it experiences a later natural sunrise and sunset, residents follow the same official clock time as the capital. This single, unified time zone has been the national standard since 1949 to promote national unity and simplify communication and transportation across the country.
