The presentation discusses Daylight Saving Time (DST), which is the practice of setting clocks forward by one hour during the summer months to extend evening daylight. Initiated by Benjamin Franklin in 1784, DST begins in the U.S. on the second Sunday of March and ends on the first Sunday of November, although not all countries observe it. The pros of DST include energy savings and increased recreational time, while the cons involve sleep disruption and potential inefficiencies for non-participating regions.

13. Daylight Saving Time Law
13
A A Shahreyar Antu
Federal law requires states to have Daylight Saving Time from
early March to early November and standard time the rest of the
year (about four months). However, states are permitted to have
standard time all year, without federal approval. Hawaii and
Arizona stay on standard time all year.

14. The Pro’s of Daylight
Savings Time:
14
The pros are that when used, Daylight
Savings help save energy and sleep time.
It also helps save money because as
people stay out of their house longer
because they can enjoy longer daylight
hours, less energy is being consumed and
therefore utility bills are lower.
A A Shahreyar Antu

15. The Con’s of Daylight
Savings Time:
15
The cons for the people who don’t use it,
they waste money, time and energy.
Also, it wastes sleep time and body
energy.
