Daylight saving time in Mexico
Most of Mexico no longer observes daylight saving time (DST; Spanish: horario de verano ("summer schedule")) as it was abolished on Sunday, 30 October 2022.[1] The exceptions are the entire state of Baja California, as well as the border municipalities in Chihuahua, Coahuila, Nuevo León, and Tamaulipas which still observe daylight savings time matching the schedule of the United States beginning on the second Sunday of March and ending on the first Sunday of November.[1]
From 1996 to 2022, DST was observed even in its tropical regions, because of its increasing economic ties to the United States. It observed the schedule used by the United States prior to 2007, with DST beginning on the first Sunday of April and ending on the last Sunday of October.[2] Although the United States changed the schedule for DST beginning in 2007, only certain municipalities located less than 20 km from the border adopted this change. [citation needed]
Overview
[edit]The state of Baja California adopted daylight saving time in 1942, due to the state's close ties to the U.S. state of California. This made Baja California the first Mexican state to observe daylight saving time.[3]
The Government of Mexico adopted daylight saving time nationwide in 1996 to decrease energy consumption and to facilitate commerce and tourism with the neighboring United States.[4][5]
In December 2009, Congress gave permission to the municipalities located less than 20 kilometers from the US border to synchronize their time to that of their US counterparts, resulting in these municipalities joining and leaving DST at the same time as the United States, relieving some border problems and confusion.[6]
- Matamoros, Tamaulipas
- Reynosa, Tamaulipas
- Nuevo Laredo, Tamaulipas
- Anáhuac, Nuevo León
- Acuña, Coahuila
- Piedras Negras, Coahuila
- Ojinaga, Chihuahua
- Juárez, Chihuahua
- All of Baja California
Apart from the border municipalities (above), daylight saving time for Mexico began the first Sunday of April, and ended last Sunday of October.[citation needed]
A bill was proposed by Rep. Francisco Saracho (PRI) in September 2015 to reduce confusion by modifying the aforementioned DST start and end dates, observed by the rest of the country, to match those observed by the border municipalities (above). The bill was discarded by congress on 29 June 2016.[citation needed]
In July 2022, President Andrés Manuel López Obrador proposed a bill to eliminate Daylight Saving Time, after results of a survey showed that 71% of the general public supported the idea. Certain northern border municipalities will continue the practice to remain harmonized with adjacent US states.[7] This bill was passed on 26 October 2022 and came into effect on the following Sunday, 30 October 2022, so that clocks will stay on standard time permanently after that Sunday's shift from daylight time.[1]
Baja California
[edit]The state of Baja California (not Baja California Sur) has observed daylight saving time from several decades ago and until 1996 was the only Mexican state to observe it.[2]
As of 2022, Baja California is the only state that continues to observe DST statewide instead of along a limited border region.[citation needed]
Sonora
[edit]The state of Sonora has not observed DST since 1998 because of the non-observance of DST by most of its neighbor Arizona and its important economic ties with that US state.[2]
Island territories
[edit]The Marías Islands and the Revillagigedo Archipelago do not observe DST. The westernmost island of the Revillagigedo Archipelago, Clarion Island, uses UTC−08:00 (PST) all the time.[citation needed]
Quintana Roo
[edit]The state of Quintana Roo decided to not observe DST from 1 February 2015, when it switched time zones from CST to EST.[8]
