Time is one of the most important ways through which humans organise their daily lives. From school schedules to office work and travel, almost every activity in modern society follows a fixed time structure.
Over the years, different countries have introduced several systems and adjustments to make better use of daylight and improve the efficiency of daily routines.
One interesting concept is Daylight Savings Time. It is a system that changes the clock during certain periods of the year. The idea behind it is to adjust the clock so that people can make better use of natural daylight during longer days.
Many competitive exams and quizzes include questions about global practices, time systems, and historical developments related to DST. Understanding the basics of this concept can therefore help students improve their knowledge of international practices and global time systems.
