What is daylight saving time?
Daylight saving time is a time adjustment measure that consists of moving the clocks forward by one hour starting in the spring, usually in March, and moving them back again in the fall, often in November.
The main purpose of this measure is to extend the duration of daylight in the evening, thus reducing energy consumption related to artificial lighting. Although widely practiced in many countries, it remains controversial due to its varying impact on local economies and lifestyles.
