As the sun returns and the winter blues float away, it’s almost time to adjust the American clock. Daylight Saving Time (DST), a practice of changing your clock twice a year, has a long history full of controversy, diplomacy, and some unique quirks depending on where you live.
Despite its routine nature, DST means longer evenings to enjoy the sun in the end. So, as the date approaches, we’ve gathered all the information you need to know, including when to change the clocks, why it happens, and why some want to do away with DST altogether.
When will the clocks change in March 2025?
For Americans, the time changes on Sunday, March 9th. It will happen at 2 am local time, moving forward by one hour.
This marks the start of DST, but the transition may vary depending on your location. Here’s how it looks in major cities:
- Los Angeles: Along with other West Coast cities like Seattle and San Francisco, will shift from standard Pacific time to daylight Pacific time. The sunrise will move from 6:15 am to 7:15 am, and the sunset from 5:54 pm to 6:54 pm.
- Chicago: Will transition from Central Standard Time to Central Daylight Time. The sunrise will change from 6:17 am to 7:17 am, and the sunset from 5:47 pm to 6:47 pm.
- New York and Washington DC: Will switch from Eastern Standard Time to Eastern Daylight Time. This will shift the sunrise from 6:22 am to 7:22 am, and the sunset from 5:53 pm to 6:53 pm.
How does daylight saving time work?
The concept of Daylight Saving Time is fairly simple. Every year, we adjust our clocks by adding or subtracting an hour. This occurs twice a year and alternates between the two.
These time changes are known as Daylight Saving Time and Standard Time. DST begins in March, moving us forward an hour, ends in November, and then moves back an hour.
On the surface, this may seem strange, but it serves a purpose. DST aims to make better use of sunlight and save energy by providing more daylight in the evening, allowing for more time to enjoy the sun and reducing electricity demands at home.
What is the history of daylight saving time?
The history of Daylight Saving Time dates back quite a long time. While often attributed to Benjamin Franklin in 1784, the actual origins can be traced back before 1907.
William Willett, an advocate for more daylight hours, proposed changing how we view time. This proposal, involving moving the clock forward by 80 minutes in four increments of 20 minutes each Sunday at 2 am, eventually led to the establishment of Daylight Saving Time.
Since then, the system has been refined and simplified. Despite initial resistance, DST eventually became a standard practice in 1966.
Why do some people want to abolish daylight saving time?
Aside from the inconvenience of changing the clock annually, there are reasons why some advocate for the abolishment of DST.
Studies suggest that clock changes can have a negative impact on health, with an increased risk of heart attacks following the spring time change. Additionally, the economic cost of DST changes is estimated to be significant, affecting productivity.
Another important reason is the impact on pets. It’s recommended to gradually adjust your pet to the time change to avoid disruptions to their routines.
