It is an imaginary line that is drawn through the Pacific Ocean where the calendar day begins. In your case, when traveling east, 24 hours is subtracted from the current time.
EX: If the local time just east of the line is 5:00 AM on July 11, 2011 the local time is 5:00AM on July 10, 2011
Hope this helps :)
It's not essential to cross the IDL in order to get from Auckland to LA ... since
the Earth is spherical, you can head west from Auckland and reach LA eventually.
But it's certainly a shorter trip if you make it an easterly one and cross the line
on your way. When you do cross the line, leave the time on your wristwatch
alone, but turn the date back one day. That is, if the date reads June 13th as
you cross the IDL, change it to read June 12th.
If you cross the International Dateline while traveling from Asia or Australia to
North or South America, that is, in an easterly direction, then the right thing
to do as you cross the line is to replace the last daily page you tore off of your
calendar, turn your calendar wrist watch back one day, reset the date in your
laptop to one day earlier, etc.
You either gain or lose a day - depending on which direction you're travelling.
NZ002 leaves Auckland at 22:30 and arrives in London Heathrow at 11.00am (1 day later due to crossing the international date line).
That depends on where you are travelling from and if you are crossing any international borders. For example, if you are travelling within the U.S, you do not need a passport to go to El Paso. However, if you are travelling from Canada to El Paso, a valid Canadian passport is required.
it will ruin everything!
Crossing the international date line. or By travelling on a vehicle called "Wednesday". and why do you waste your time doing dumb riddles?
Auckland is 22 hours ahead of Rarotonga when New Zealand is on Standard Time and 23 hours ahead during Daylight Saving Time.Daylight Saving Time in New Zealand begins on the last Sunday of September at 02:00 NZST and ends on the first Sunday of April at 03:00 NZDT.
Since the Earth is spherical (shaped like a ball), you can head out of Rarotonga in either direction, either east or west, and eventually wind up in Auckland. The trip is quite a bit shorter, though, if you travel westward, and that will take you across the International Date Line. At the moment of crossing the line, the right things to do are to advance your calendar by one day, and turn your clock ahead 24 hours. For example, if it happens to be 3:00 PM on Tuesday, then it becomes 3:00 PM on Wednesday when you cross the line. In reality, there's no need to make the adjustment exactly as you cross the line. Passengers typically make the change when they board the ship or plane, or when they disembark at the end of the trip. As long as you're actually at sea or in the air, it really doesn't matter much what day it is.
travelling by ships (crossing the Atlantic ocean)
Traveling from Auckland to Los Angeles, you will turn your watch back 24 hours, andtake the last page you tore off of your calendar and glue it back on, allowing you tolive the same date all over again. You will most likely not make the same mistakesagain, but will have the opportunity to make new ones.
the clocks
Crossing the International Date Line travelling to the east results in a day or 24 hours being subtracted from your time prior to arriving at that position, so that the you have to repeat the date to the west of the line. Crossing west results in a day being added, that is, the date is the eastern side date plus one calendar day. The line is necessary in order to have a fixed boundary on the globe where the calendar date resets
If travelling Easterly, the main ocean is the Pacific. If travelling Westerly, the main ocean is the Atlantic. Either direction of travel means crossing lesser oceans.
