Time
Puerto Vallarta, Guadalajara, and the rest of Jalisco State fall into Central Standard Time (the same as Mexico City). Nayarit and other parts of the northwest coast are on Mountain Standard Time.
However, Nuevo Vallarta, Bucerías, La Cruz de Huanacaxtle, Punta de Mita, and most of the Riviera Nayarit have been adjusted to stay in the same time zone as Puerto Vallarta, avoiding the confusions of past years. Bear in mind that Mexico does observe daylight saving time, but not on the same schedule as the United States.
