Mexico has recently made a historic decision to cancel Daylight Saving Time (DST) in most of the country. The decision came after years of debate and discussions among government officials and citizens alike. The change took effect in 2023 and is expected to have a significant impact on the country's economy, social life and energy consumption.
Mexico has a long and complicated history with DST. The country first implemented DST in 1996 as a way to save energy, reduce crime rates and stimulate tourism. However, the policy has been controversial ever since. Many citizens complained that the change disrupted their sleep patterns and had a negative impact on their health and well-being. Others argued that it had no real impact on energy consumption or crime rates and that it only caused confusion and chaos.
In recent years several states in Mexico began to reject DST and refused to follow the federal government's policy. These states argued that the practice was outdated and unnecessary and that it caused more harm than good. In 2020 the state of Sonora became the first state in Mexico to permanently cancel DST. Other states soon followed suit and now most of the country has decided to abandon the practice altogether.
Starting in 2023, Mexico will no longer observe DST in most of the country. Only a few border cities that have close ties with the United States such as Tijuana and Mexicali will continue to follow the DST policy. The change is expected to have a significant impact on the country's economy, especially in the tourism and transportation sectors. It is also expected to have a positive effect on public health as people will be able to maintain more consistent sleep patterns and avoid the negative effects of changing their sleep schedules twice a year.
