Since the Earth rotates continuously, different places experience different local times. To avoid confusion and maintain a uniform system of dates and time across the world, the International Date Line plays a significant role. Through this chapter, students learn how time and dates are managed globally.
The International Date Line is an imaginary line located approximately along 180° longitude in the Pacific Ocean. It serves as the boundary where the calendar date changes by one day. Crossing the line from east to west adds one day, while crossing it from west to east subtracts one day.
The International Date Line does not follow the 180° longitude exactly. It bends at various locations to avoid dividing countries and island groups into different calendar dates.
This chapter helps students understand how different countries maintain accurate time and date systems despite being located in different parts of the world. It explains the relationship between longitude, time calculation, and date changes.
