The Purpose of DST
The primary goal of DST is to extend daylight into the evening hours during summer. By "borrowing" an hour of daylight from the morning, people can enjoy longer evenings with natural light, which is believed to save energy and promote outdoor activities.
How It Works: "Spring Forward, Fall Back"
- Spring Forward: In the spring, clocks are advanced by one hour (e.g., from 2:00 AM to 3:00 AM). This marks the beginning of DST.
- Fall Back: In the autumn, clocks are set back by one hour (e.g., from 2:00 AM to 1:00 AM), returning to standard time.
Not all countries or regions observe DST. For example, Japan, India, and China do not use it. In the United States, states like Arizona and Hawaii do not observe DST.
Conclusion
Daylight Saving Time is a seasonal time change practice that affects scheduling and time conversion in many parts of the world. It's a key reason why checking the exact local time is important. Our World Clock and other tools automatically account for DST changes.
