Daylight Saving Time in Mexico

In most of Mexico, Daylight Saving Time is known as Horario de Verano (summer schedule). It has been observed since 1996 throughout most of the country.

Until April of 2010, the state of Nayarit was one hour earlier than Puerto Vallarta and the state of Jalisco. Before that, many tourist related businesses in Nayarit around Banderas Bay would set their clocks to Puerto Vallarta time to prevent confusion. On April 4, 2010, Nayarit initiated a 2 hour time change to coincide with Jalisco.

Therefore, in both states on April 3, 2011, the clocks will be turned forward 1 hour from 2:00 am to 3:00 am. Daylight Saving Time will end on Sunday, October 30, 2011.
