Question
What is International Date Line ?
Answer
The International Date Line (IDL) is an imaginary line on the Earth’s surface that roughly follows the 180 degrees longitude line and serves as the divide between two consecutive calendar days. When you cross the IDL, you either gain or lose a calendar day, depending on the direction of your travel. The IDL is important because it helps to maintain a consistent global timekeeping system by ensuring that the same calendar day is being observed across the world at any given time.
