Chile Gears Up for Summer Time Change in September 2025
santiago, Chile – As Winter embraces Chile, with daylight hours at their shortest, preparations are underway for the transition back to Summer time. Chile implements a bi-annual time change to maximize the use of daylight, adjusting clocks to optimize energy consumption.
The current Winter time schedule, which began on April 5th with clocks moving back one hour, is set to conclude in early September. Here’s what you need to know about the upcoming change and how it might affect you.
When Will Clocks Spring Forward?
According to current regulations, the Winter time schedule will remain in effect until Saturday, September 6, 2025. On this date, which marks the frist Saturday of September, clocks will be moved forward by 60 minutes. This means that at midnight on Saturday, September 6th, clocks will jump ahead to 1:00 AM on Sunday, September 7th.
Exempt Regions: Who Stays on Summer Time?
Not all regions of Chile participate in the time change. The Aysén Region, Magallanes, and Chilean Antarctica will maintain Summer time throughout the year. Residents and travelers in these areas will not need to adjust their clocks.
For the rest of the country, here is a summary
Regions Observing the Time Change
- From the Arica and Parinacota region to the Los Lagos region.
- Occidental Insular Chile, Easter Island and Isla Salas and Gómez.
Understanding Daylight Saving Time
Daylight Saving Time (DST), often referred to as Summer time, is the practice of advancing clocks during the warmer months so that darkness falls later each day. The primary goal is to make better use of daylight and conserve energy. By moving the clocks forward, people can enjoy an extra hour of daylight during the evening, reducing the need for artificial lighting.
the concept was first proposed by Benjamin Franklin in 1784, but it wasn’t until World War I that it was widely adopted as a means to save energy. Germany was the first country to implement DST in 1916, followed by the United Kingdom and other European countries.
Did You Know? Some studies suggest that DST can lead to a decrease in traffic accidents and crime rates due to increased visibility during evening hours.
Benefits and Drawbacks of Time Change
While DST is intended to save energy,its effectiveness is still debated. Some studies have shown that the energy savings are minimal, while others suggest that DST can actually increase energy consumption due to changes in heating and cooling patterns.
Regardless, the practice continues in many countries around the world, including parts of North America, Europe, and Australia. each region sets its own DST schedule, with start and end dates varying from country to country.
Pro Tip: To minimize the impact of the time change,gradually adjust your sleep schedule in the days leading up to September 6th. This can help your body adapt more easily to the new time.

The History of Daylight Saving Time
The idea of Daylight Saving Time isn’t new. benjamin Franklin proposed a similar concept in 1784, suggesting that people could save candles by getting up earlier in the summer and making use of the morning daylight.
Though, the modern concept of DST is credited to William Willett, a british builder, who in 1907 proposed advancing clocks by 80 minutes in the summer to take advantage of daylight. His idea was initially met with resistance but gained traction during World War I as countries sought ways to conserve energy.
Germany was the first country to implement DST on April 30, 1916, during World War I. Shortly thereafter, the United Kingdom followed suit on May 21, 1916. The United States adopted DST in 1918 but repealed it in 1919.It was then used again during World War II and has been used intermittently since then.
Global Adoption of daylight Saving Time
Not all countries observe Daylight Saving time, and those that do may follow different schedules. In Europe, DST is observed in most countries, with clocks moving forward on the last Sunday in March and back on the last Sunday in October.
In North america,the United States and Canada observe DST,but some states and provinces have either opted out or are considering doing so. Arizona and Hawaii do not observe DST, and several states have introduced legislation to make DST permanent.
The debate over the benefits and drawbacks of DST continues, with proponents arguing that it saves energy and promotes outdoor activities, while opponents cite disruptions to sleep patterns and potential health risks.
