How does daylight saving time affect time zones?

What is daylight saving time and why do we have it?

Daylight saving time (DST) is the practice of setting the clock forward by one hour during warmer months to extend evening daylight. It was introduced to make better use of daylight and conserve energy.

How does DST affect different time zones?

DST affects time zones by shifting the local time forward or backward, which can create discrepancies between regions that observe DST and those that do not.

Can you give me an example of how this works?

Sure! For instance, if New York observes DST and moves the clock forward one hour, while Los Angeles does not, the time difference between them changes from 3 hours to 2 hours during DST.

Are there places that don’t observe daylight saving time?

Yes, several regions, including parts of Arizona and Hawaii in the U.S., do not observe DST, which can lead to confusion in scheduling.

What are the arguments for and against daylight saving time?

Proponents argue it saves energy and promotes outdoor activities in the evening, while opponents claim it disrupts sleep patterns and has minimal energy savings.
