International Date Line : Interesting Facts

The international date line, laid out in 1884, goes through the mid-Pacific Sea and generally follows a 180-degree-longitude north-south line on the Earth. It is found most of the way all over the planet from the prime meridian — the 0-degree longitude queue in Greenwich, Britain.

The worldwide date line works as a “line of demarcation” isolating two back-to-back schedule dates. At the point when you cross the date line, you become a person who jumps through time of sorts! Cross toward the west, and it’s one day after the fact; cross back, and you’ve “travelled once again into the past.”

In this article, we shall know about it more. Let’s dive right in!

Where Is the International Date Line?

The Worldwide Date Line (IDL) is situated at around 180° east (or west). It is most of the way all over the planet from the excellent meridian (0° longitude), the reference point of time regions, which goes through Greenwich, UK.

The date line runs from the North Pole toward the South Pole and denotes the Western and Eastern Half of the globe partition. It isn’t straight, however, bends around expanses of and masses and national borders. For instance, it inclines towards the east at the Bering Waterway among Asia and North America, leaving Cape Dezhnev in Russia daily in front of Cape Ruler of Ribs in Gold country despite the fact that they are just 80 km (50 mi) separated.

Different Days on Either Side:

For instance, Kiribati and Hawaii are on various sides of the date line. Assuming you went from Kiribati’s capital Tarawa to Hawaii’s state capital Honolulu, you would need to turn the clock back 22 hours, successfully turning back the clock, to some degree on the schedule.

Not Always 24 Hours:

Contingent upon which time region the nation follows, the time contrast on one or the other side of the line isn’t generally 24 hours. For instance, on the off chance that you venture to every part of the 1061 km (659 mi) across the date line from Bread cook Island to Tokelau, you should add 25 hours, or 1 day and 60 minutes.

Three Dates at the Same Time:
