At what longitude is the International Date Line located?

The International Date Line is situated at a longitude of 180°. This imaginary line serves as the boundary for calendar dates, indicating where one day ends and the next one begins. When you cross the International Date Line from west to east, you subtract a day, and when you cross from east to west, you add a day. This system helps manage time zones around the globe, ensuring that, despite latitude and cultural differences, there is a standardized way of keeping track of time and days internationally. Understanding the significance of the International Date Line is crucial for grasping how we define and organize time across different regions of the world.
