Don't be late for your Easter date! If you are lucky enough to be spending the holidays here in Puerto Vallarta, be sure to set your clocks ahead one hour before going to bed on Saturday night.

Puerto Vallarta, Mexico - Daylight saving time, usually referred to as the Horario de Verano in Mexico, begins at 2:00 am local time on Sunday, April 5, 2015. So if you are lucky enough to be spending the Easter holidays here in Puerto Vallarta, don't forget to set your clocks ahead one hour before going to bed this Saturday night!

Daylight Saving Time in Mexico

In Mexico, daylight saving time begins at 2:00 am local time on Sunday, April 5, which means most everyone will be turning their clocks ahead one hour. Some Mexico border communities changed their clocks on March 8th in accordance to the U.S. time change. (For more information, click HERE.)

Mexico adopted DST nationwide in 1996, even in its tropical regions, because of its increasing economic ties to the United States. Although the U.S. changed the schedule for DST beginning in 2007, most of Mexico did not go along with it. Daylight saving time for Mexico begins on the first Sunday of April, and ends on the last Sunday of October.

In 2010, the ten Mexican municipalities that share a border with the United States started to observe daylight saving time three weeks earlier, on the second Sunday in March and ending on the first Sunday in November. This change in daylight saving time observance was requested by local governments and political leaders to help facilitate commerce with the United States.

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 clocks will be turned forward 1 hour from 2:00 am to 3:00 am on April 5, 2015. Daylight Saving Time will end in Mexico on Sunday, October 25, 2015.

5 Myths about Daylight Saving Time

Daylight saving time (DST) will begin in México on April 5, the first Sunday in April, except for the municipalities located less than 20 kilometers from the USA border. Those municipalities changed to DST on March 8, the second Sunday in March, along with the United States and Canada.

Although the United States adopted DST in 1986, México did no adopt it until 1996. Prior to 1996 the state of Baja California was the only state to observe DST. The state of Sonora has never adopted DST because of the non-observance of DST by Arizona and its important economic ties with that US state.

This will be the first year in which the state of Quintana Roo will not observe DST. That state also changed its time zone this year from Central Standard Time to Eastern Standard Time.
Many people are confused about the origin, which has created several myths. A few of them are:

• Daylight saving time was meant to help farmers.

This comes from the idea that more daylight means more time in the field for farmers. Michael Downing, who wrote a book about DST, says “The farmers were the reason we never had a peacetime daylight saving time until 1966. They had a powerful lobby and were against it vociferously.” The lost hour of morning light meant they had to rush to get their crops to market.

• The extra daylight makes us healthier and happier.

Commenting on DST the U.S. Senator Ed Markey (D-Mass.), said “In addition to the benefits of energy savings, fewer traffic fatalities, more recreation time and increased economic activity, Daylight saving time helps clear away the winter blues a little earlier,” he said in a statement last year. “Government analysis has proven that extra sunshine provides more than just smiles. .?.?. We all just feel sunnier after we set the clocks ahead.”

A little more vitamin D from the sun may be healthy, but not the way DST provides it. Experts have noted that when DST starts and ends there are noticeable spikes in workplace accidents, suicide and headaches. One 2009 study found a 5.7 percent increase in injuries among mine workers in the week after the start of DST, which researchers believe is most likely due to disruption in the workers’ sleep cycles. An Australian study found a slight uptick in male suicides in the weeks following time shifts, which the researchers blamed on the destabilizing effect of sleep disruption on people with mental health problems. Some physicians say that changes in circadian rhythm can trigger cluster headaches, leading to days or weeks of discomfort.

• It helps us conserve energy.

Representative Fred Upton from Michigan said, “An annual rite of spring, daylight saving time is also a matter of energy conservation. By having a little more natural daylight at our disposal, we can help keep daily energy costs down for families and businesses.”

A study by the California Energy Commission found the energy savings to be a paltry 0.18 percent. An Indiana study found a slight increase in energy use after the entire state adopted DST; the researchers believed that more air conditioning in the evening was largely to blame.

Daylight Savings Time Ends in Mexico This Weekend

Daylight saving time officially ends for most of Mexico at 2 am this Sunday, October 26, 2014. If you are here in Puerto Vallarta, be sure to set your clocks back one hour before going to bed Saturday night.

Puerto Vallarta, Mexico - There are just a couple of days left before we get that opportunity for an extra hour's sleep in the morning. That's right, daylight saving time 2014 officially ends for most of Mexico at 2 am on Sunday, October 26th - this weekend! That means you need to set your clock back one hour before retiring on Saturday night.

Since Mexico did not go along with the changes that the United States made to established daylight savings time in 2007, it's important to note that the shift to standard time in Mexico will take place a week earlier than in the US, something visitors may find useful to know - especially those arriving by cruise ship or airplane.

Equally important, it is also a good time to check the batteries in your smoke detectors while you are changing your clocks.

Are there health issues with the changing of time?

For many of us, the return to standard time can be depressing. The day seems to fly by and it's dark before it's time to start thinking about dinner. But many doctors say the return to standard time can be healthy.

"Generally, it is always easier to stay up an hour later than to go to sleep an hour earlier, so most people have relatively little problem setting the clocks back in the fall," said Dr. Steven Feinsilver, director of the Center for Sleep Medicine at Mount Sinai School of Medicine in New York. "This is because our basic circadian rhythm (the 'body clock') actually seems to be programmed for a longer than 24 hour day. It runs a little slow."

"The circadian clock does not change to the social change," said chronobiology researcher Till Roenneberg of Ludwig Maximilans University in Munich, Germany. "During the winter, there is a beautiful tracking of dawn in human sleep behavior, which is completely and immediately interrupted when daylight saving time is introduced in the spring."

Roenneberg, lead researcher for a study of the effects of time shifts, said that humans' biological clocks are stronger than the clocks set by man-made laws.

"When you change clocks to daylight saving time, you don't change anything related to sun time," Roenneberg said. "This is one of those human arrogances, that we can do whatever we want as long as we are disciplined. We forget that there is a biological clock that is as old as living organisms, a clock that cannot be fooled. The pure social change of time cannot fool that clock."

Though individuals may see their biological clocks reset, and will get an "extra hour" of sleep or rest over the weekend, researchers say that the stress caused by time changes can be bad for the body.

Researchers in Sweden published a report in 2008 in the New England Journal of Medicine reporting that the number of heart attacks jumps during the period immediately following time changes, and that those vulnerable to sleep deprivation should be extra careful.

"More than 1.5 billion men and women are exposed to the transitions involved in daylight saving time: turning clocks forward by an hour in the spring and backward by an hour in the autumn," wrote Imre Janszky and Rickard Ljung, health and welfare researchers in Sweden. "These transitions can disrupt chronobiologic rhythms and influence the duration and quality of sleep, and the effect lasts for several days after the shifts."

Janszky and Ljung said that sleep deprivation can affect the cardiovascular system, leading the vulnerable to have heart problems in the days following the daylight savings time changes.

MÉXICO (UNIV)._ El próximo domingo 6 de abril inicia el Horario de Verano en la mayor parte de la República mexicana, por los que se recomienda que el sábado 5, antes de dormir, se adelante el reloj una hora, de modo que al día siguiente se reanuden actividades con el nuevo horario.

Según el Fideicomiso para el Ahorro de Energía Eléctrica, el año pasado, el ahorro de electricidad fue de mil 224 gigawatts por hora (GWh), equivalente al consumo anual de energía eléctrica del estado de Nayarit, lo cual se tradujo en un ahorro de mil 635 millones de pesos.

En materia ambiental se evitó la emisión de 595 mil toneladas de bióxido de carbono, así como la quema de 771 mil barriles de petróleo crudo, tomando en cuenta que gran parte de la energía que se consume en el país se generó a partir de combustibles fósiles.

De acuerdo con datos de la Secretaría de Energía, los ahorros acumulados por la aplicación del Horario de Verano desde su inicio a la fecha, permitieron disminuir en 20 mil 684 GWh el consumo de electricidad.

"A fin de dimensionar el significado del ahorro de energía acumulado de 1996 a la fecha por la aplicación del horario de verano, esa energía ahorrada sería suficiente para abastecer el consumo eléctrico de 11.9 millones de hogares durante todo un año (con un consumo promedio de 289 kwh bimestrales por hogar)", detalló en un comunicado.

En México, el Horario de Verano inicia el primer domingo de abril y concluye el último domingo de octubre, excepto en los 33 municipios de la franja fronteriza norte, en donde se aplica del segundo domingo de marzo al primer domingo de noviembre.

Mexico Not 'Springing Forward' Until April 6, 2014

In Mexico we won't be setting our clocks forward until the first Sunday of April.

Puerto Vallarta, Mexico - While Americans will be turning their clocks ahead for daylight-saving time on Sunday, March 9, 2014, for most of Mexico, daylight saving time does not begin until 2:00 a.m. local time on Sunday, April 6th. So make a note if you'll be traveling to Mexico this month - there will be an extra hour difference in time.

Daylight Saving Time in the United States

Daylight Savings Time (DST) begins in the United States on the second Sunday in March and ends on the first Sunday in November. So this Sunday, March 9, 2014, US clocks will be set ahead one hour at 2:00 a.m. local standard time, which becomes 3:00 a.m. local daylight time.

Daylight Saving Time in Mexico

For most of Mexico, daylight saving time doesn't begin until the first Sunday of April, and won't end until the last Sunday of October. It is usually referred to as the Horario de Verano (Summer Schedule).

Mexico adopted DST nationwide in 1996, even in its tropical regions, because of its increasing economic ties to the United States.

Although the United States changed the schedule for DST beginning in 2007, most of Mexico did not go along with it.

But in 2010, the ten Mexican municipalities which share a border with the United States started to observe daylight saving time three weeks earlier, on the second Sunday in March and end on the first Sunday in November. This change in daylight saving time observance was requested by local governments and political leaders to help facilitate commerce with the US.

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 6, 2014, the clocks will be turned forward 1 hour from 2:00 am to 3:00 am. Daylight Saving Time will end on Sunday, October 26, 2014. 

 

 

Daylight Savings Time Ends Sunday Morning

The shift to standard time in the USA will occur on November 3rd.

The Department of Energy (Sener) announced that daylight saving time for 2013 officially ends for most of México at 2 am on Sunday, October 27th (this weekend). That means everyone needs to set their clocks back one hour before retiring on Saturday night.

Since México did not go along with the changes that the United States made to established daylight savings time in 2007, it’s important to note that the shift to standard time in México will take place a week earlier than in the US, which will occur on November 3^rd.

Sener said that in economic terms, it is estimated that the implementation of Daylight Saving Time saves México 1.635 billion pesos ($126 million) a year.

Sener noted that “33 municipalities in the northern border zone follow the Daylight Savings schedule of the United States in order to facilitate the daily lives of local residents, who have to cross back and forth over the border every day for work or school.”

MÉXICO (NTX)._ El próximo domingo 27 de octubre, a las 2:00 horas concluirá el Horario de Verano 2013, por lo que se sugiere a la población que el sábado 26, antes de irse a dormir, retrase una hora los relojes para que al día siguiente reanuden sus actividades con el nuevo horario.

En un comunicado, la Secretaría de Energía estimó que con la aplicación del Horario de Verano dejará un ahorro de mil 635 millones de pesos y se evitó la emisión a la atmósfera de 560 mil toneladas de bióxido de carbono, principal causante del efecto invernadero.

De acuerdo con datos preliminares del Fideicomiso para el Ahorro de Energía Eléctrica, elaboradas con información de la CFE y la valoración del Instituto de Investigaciones Eléctricas, la contribución del Cambio de Horario de Verano este año se estima en 1244 Gigawatts-hora.

Esta cifra es equivalente al consumo de 704 mil casas habitación durante un año, considerando 289 Kilowatts-hora bimestrales de consumo promedio por hogar e incluye los ahorros obtenidos en los 33 municipios de la franja fronteriza norte, que adoptan el Horario de Verano el segundo domingo de marzo y concluyen el primer domingo de noviembre.

La Sener puntualizó que algunos de los 33 municipios donde la aplicación del Horario de Verano concluirá el próximo domingo 3 de noviembre, son Tijuana, Mexicali, Ensenada, Playa Rosarito y Tecate, en Baja California. Juárez, Ojinaga, Ascención, Coyame del Sotol, Guadalupe, Janos, Manuel Benavides y Praxedis G. Guerrero, en Chihuahua.
