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.
If it is midnight in Greenwich, England, then it is midday on the International Date Line because the International Date Line is halfway around the world and separates one calendar day from another.
The day begins at the International Date Line in the Pacific Ocean, located roughly opposite the Prime Meridian. This imaginary line marks the boundary between two consecutive calendar days. When it's midnight at the International Date Line, the day officially starts there.
At the single instant in time when the calendar date is the same everywhere on earth, the time on the International Date Line is 12:00 midnight, and it's the beginning of that day on the east side of the line, and the end of the same day on the west side.
The difference between the two is that a Golden Shellback has crossed the Equator at the International Date Line (00.00 N and 00.00 E)
The Midnight Meridian refers to the line of longitude directly opposite the Prime Meridian, marking the halfway point between the International Date Line and the Prime Meridian. It is where each calendar day begins.
When the international date-line and midnight line up (once a day).
1 day
Midnight.
Because when flying either to Japan or America, you cross the International Date Line.
The maximum time difference between two locations on Earth is 24 hours, which occurs when they are on opposite sides of the International Date Line.
International was released at a later date. The most notable differences are the addition of Dark Aeon bosses and the boss Penance.
The International Date Line is the meridian where the date changes by one day when crossed east to west. This happens in order to account for the time difference between different parts of the world. Crossing the International Date Line from east to west, you "gain" a day, and crossing from west to east, you "lose" a day.
