Daylight saving time (DST) is the practice of setting the clock forward by one hour during the warmer months of the year, typically in spring, and setting it back again in autumn to standard time. This is done to make better use of daylight and to conserve energy.
The idea behind daylight saving time is to shift the hours of daylight to the evening, when people are typically more active, thus reducing the need for artificial lighting in the evenings. It was first proposed by Benjamin Franklin in 1784, although it wasn't widely adopted until the 20th century.
Many countries around the world observe daylight saving time, although the start and end dates can vary. Some regions do not observe DST at all. The practice has its proponents and opponents, with debates focusing on its impact on energy consumption, public health, and economic productivity.
Daylight Saving Time (DST), also known as summer time, is a practice where clocks are set forward one hour during the summer months to make better use of natural daylight. Here's a breakdown:
How it works:
- In the spring, clocks are set forward by 1 hour, making mornings darker but evenings brighter.
- In the fall, clocks are set back by 1 hour, resulting in earlier sunrises and sunsets.
Purpose:
The idea behind DST is to save energy by taking advantage of sunlight during the longer summer days. With more daylight hours in the evening, people are less likely to rely on artificial lighting.
Schedule:
- In the United States and Canada, DST typically starts on the second Sunday in March and ends on the first Sunday in November.
- This means today, on Sunday, March 10, 2024, DST actually begins! So, you'll set your clocks forward by one hour at 2:00 am.
Remembering the Change:
There's a handy saying to remember which way to set your clocks: "Spring forward, fall back."
International Use:
- DST is not observed everywhere in the world.
- Many countries, particularly near the equator where day length variations are minimal, don't use DST.
