The International Date Line separates Day 1 from Day 2 across the globe. Thus, if you are crossing the Internationa Date Line, you may be a day ahead or behind of the place you have travelled from.

How helpful is the international date line?
In a world in which people commonly travel great distances, it is necessary to have some means of keeping track of how the time of day changes in different parts of the world, and it is necessary to have an international date line. There is no absolute necessity for the international date line to be where it is; that was a reasonable choice but not the only possible choice. But we definitely need to have an international date line somewhere. At some point, the far east meets the far west, and one day becomes another day. It has to happen, for our time keeping system to make sense on a global scale. If you just stayed in the same city for your whole life, you would never need an international date line (or a passport). But in the age of jet airplanes, we travel a lot.
Which side of the international date line is the cook islands?
The Cook Islands of New Zealand are on the east side of the International Date Line, 10 hours behind UTC (the same time offset as Hawaii).
What is another name for the Greenwich Meridian?
The Greenwich Meridian or the Prime Meridian is the imaginary line on maps from which all international times are calculated. Greenwich Mean Time (GMT). The time at every point on earth is calculated with respect to Greenwich Mean Time. This practice was originated for maritime navigation and meant that ships clocks needed to be extremely accurate and well maintained.
When traveling in a westerly direction do you set the clock forward when you change time zones?
No, you turn clocks back as you travel west into other time zones, but you advance by 24 hours when you cross the international date line westward.
The dividing line for adjusting the 24-hour difference in time zones around the world is called the?
International date line.

Difference between international date line and midnight line?
If not for standard time zones, the midnight line would be the longitude directly opposite the longitude on which the sun is directly overhead. Therefore, it would be constantly circling the earth. At the moment when the sun is at its highest point in the sky as seen from Greenwich, England (noon GMT), the midnight line would coincide with the international date line. That would be the one moment per day in which local time at every point around the earth would be on the same day. In reality, the midnight line jumps from one time zone boundary to the next through the day. When it is midnight where you are, the midnight line is jumping from the first time zone boundary east of you to the first time zone boundary west of you. Since Sunday becomes Monday when the midnight line "travels" past you to the west, the same is true when you travel past the midnight line to the east. However, when you travel east across the international date line, Monday becomes Sunday. If the international date line were the 12 at the top of a clockface, the midnight line would be the hour hand.
