During the summer season Daylight Saving Time (DST) serves as a system to maximize daylight usage. This time management system operates in the United States alongside Canada and almost all European nations. The clocks across many countries will experience a one-hour advance on March 9 during 2025 while they will return the hour on November 2 of that same year.
What is Daylight Saving Time?
During summer Daylight Saving Time moves the clocks one hour ahead to maximize daylight usage. The system stimulates energy conservation by enabling people to work under sunlight during different hours of the day. The process occurs two times annually. >
- The clock is moved forward one hour in spring and summer.
- The hours advance by one hour both in the fall and during winter month periods.
When will daylight saving time start and end in 2025?

The dates for daylight saving time implementation in 2025 will be March 9th at 2:00 a.m. as well as November 2nd at the same time. >
The policy begins at 2:00 a.m. on March 9, 2025 (Sunday) through one-hour clock advancement.
The period from November 2 2025 will end at 2:00 a.m. (Sunday) when clocks will shift backward by one hour.

Advantages and Disadvantages of Daylight Saving Time
Advantages:
- Decreased Energy Use Occurs When Additional Evening Light Becomes Accessible.
- People extend their shopping and outdoor participation under daylight while contributing to economic growth.
Disadvantages:
- The natural body time cycle called circadian rhythm faces potential disruption thus leading to an increase of stress levels and fatigue.
- Sleep problems emerge from time changes because humans need time to adapt to these changes in their sleep patterns.

Caffeine together with alcohol acts negatively on sleep quality.
Conclusion
Daylight Saving Time functions as an energy conservation method which extracts the most out of daytime illumination during summer months. The adjustment causes health-related impacts as well as sleep disturbances. The lack of Daylight Saving Time implementation in India requires businesses to maintain awareness about their international communication schedule.
