The International Date Line (IDL) is the line extending between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180.0° line of longitude and deviating …

The International Date Line (IDL) is located at about 180° east (or west). It is halfway around the world from the prime meridian (0° longitude), the reference point of time zones, which runs through Greenwich, UK. The date line runs from the North Pole to the South Pole and marks the Western and Eastern Hemisphere divide.

International Date Line, imaginary line extending between the North Pole and the South Pole and arbitrarily demarcating each calendar day from the next. It corresponds along most of its length to the 180th meridian of longitude but deviates occasionally to avoid dividing closely associated geographic entities.

2021年4月4日 · What Is The International Date Line? The IDL is an imaginary line that roughly follows the 180° line of longitude and passes through the Pacific Ocean. However, this line is not straight and strays from the 180° meridian at certain points. In some places, it appears as zig-zag, deviating to the meridian’s east or west.

The International Date Line (IDL), also known as just the Date Line, is an imaginary line on the surface of the Earth, going from north to south in the Pacific Ocean. The date becomes one day later as one travels across it in western direction, and one day earlier as one travels across it in eastern direction.

2021年7月18日 · What is the International Date Line? The International Date Line Map shows an imaginary line running from the North pole to the South pole, corresponding its length to the 180th meridian on the surface of the earth.

The International Date Line (IDL) is an imaginary boundary, running from the North Pole to the South Pole. It lies mainly along the 180° longitude in the Pacific Ocean. While this line is not straight, it bends to accommodate international borders and territories. For example, it zigzags around nations like Fiji and Samoa, so travelers can ...

2025年2月22日 · The International Date Line (IDL) is a crucial, yet often misunderstood, concept in global timekeeping. Its importance lies in its function as the arbitrary demarcation line where each new calendar day begins.

2025年2月17日 · The answer is: the IDL is roughly based on the 180° meridian of longitude. It’s important to highlight the word ‘roughly’ because, as we will explore, the line isn’t perfectly straight and deviates in several places. The 180° meridian itself is a line of longitude, running north-south through the Pacific Ocean.

THE INTERNATIONAL date line (IDL) is the imaginary line on Earth slicing through the center of the PACIFIC OCEAN that separates two consecutive calendar days. Countries in the Eastern Hemisphere to the left of the line up to the Prime Meridian are always one day ahead of countries to the right of the line and west of the prime meridian.
