International Date Line

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 IDL roughly follows the meridian of 180° longitude.

As a merciful favor to the inhabitants of countries that sit across the 180° meridian ... and people

who might want to travel to those countries ... the line was zig-zagged in order to let each country

have the same calendar date everywhere in the country.

Can you imagine what life would be like in a country that had two different calendar dates ?

Think doctor's appointments, airline and hotel reservations, bank accounts, delivery of orders,

business meetings, church services, etc.

The Prime Meridian and its opposite the 180th meridian (at 180° longitude), which the International Date Line generally follows, form a great circle that divides the Earth into the Eastern and Western Hemispheres.

It doesn't cross ANY countries. That was done intentionally when the line was drawn, in order
to avoid splitting any single country, city, or island into two dates and days of the week.

The International Date Lines roughly follows the 180

No. The "Prime Meridian" (Greenwich Meridian) is 0° longitude and runs through Greenwich, England, western Europe, and Africa.

The International Date Line is on the other side of the world, at 180° longitude (east or west is the same line), and marks the start of each new calendar day. It is midnight at the Date line when it is noon at the Prime Meridian. The actual line has detours to accommodate Russia, the Aleutians, and New Zealand.

The two meridians form a circle around the planet, and each divides the Eastern Hemisphere from the Western Hemisphere.

The International Date line crosses the Arctic and Pacific oceans.

The Prime Meridian is located at 0 degrees, the international date line is not. There is only one prime meridian, there are many international date line.

The International Date Line is an imaginary line on the Earth's surface that determines the change in calendar date when crossed. It roughly follows the 180° meridian and is used to mark the transition between consecutive calendar days. Crossing the date line from east to west results in gaining a day, while crossing from west to east results in losing a day.

The time difference between Chattanooga, Tennessee, and Germany is 6 hours. Chattanooga is 6 hours behind Germany.

10 AM UK time is 2 AM Pacific time and 5 AM Eastern time.

Roughly 180o, the date line wiggles to avoid passing over inhabited land so that people don't have the complication of living with the dateline passing through their town.

Traveling west across the date line.

To determine the longitude of a place, you need to find the meridian on which it is located. This meridian is known as the prime meridian, which is the line of longitude designated as 0°. By identifying the prime meridian and calculating the distance to the location's meridian, you can determine its exact longitude.

There are 2 time zones between Sydney and the dateline (sydney is 2 hours west of the dateline). But 3 or 4 if you count Tonga which is 1 hour ahead of the dateline(west) and the Chatam islands (NZ) which is 45 minutes ahead.

From the second Sunday of March until the first Sunday of November, Guam is 15 hours ahead of Oklahoma. During the rest of the year the time difference is 16 hours.

UTC-6 = time in Oklahoma from Nov. to Mar. (CST)

UTC-5 = time in Oklahoma from Mar. to Nov. (CDT)

UTC+10 = time in Guam (ChST)

Ideally, the line should follow the meridian of 180° longitude. The purpose of the

zigs and zags is to avoid splitting a state, a country, or an island into two different

calendar dates. Imagine living on a small South Pacific island where this side of the

island and that side had two different dates. The state of Alaska would also be in

that same predicament if the Date Line followed the 180° meridian.

Depending on which way you crossed it, you either get presents twice for going into yesterday, or none for going into tomorrow.

I disagree. You should get presents for turning a new age, not for having a birthday.

It will be 6am in PST (Pacific Standard Time).

During the summer months it would be 7am (PDT - Pacific Daylight Time).

Island is observing GMT all year round and the UK in the Winter.

A stopwatch or a timer can be used to measure the time taken for the pendulum to make 20 oscillations. Start the timer when the pendulum starts swinging and stop it when it completes 20 oscillations to determine the time elapsed.

The International Date Line is an imaginary line located in the Pacific Ocean that roughly follows the 180° line of longitude. It serves as the dividing line between two consecutive calendar days and marks where each day officially begins and ends.

No. The international date line is a zig-zag line between the earth's poles. It has no particular

connection to the forces of gravity.

Gravity behaves exactly the same way at every point on earth. Wherever an object may be,

there are equal forces attracting it and the earth toward each other. The forces are proportional

to the product of the object's mass and the earth's mass, and inversely proportional to the square

of the distance between their centers. Since the earth's diameter at the equator is slightly larger than

its diameter through the poles, objects at the poles are slightly closer to the center of the earth, so

the mutual gravitational forces are slightly larger there.

I'm unable to provide personal contact information for individuals.

Yes, the International Date Line is an imaginary line that runs from the North Pole to the South Pole, roughly along the 180° meridian. It serves as the line where the date changes when crossing it, typically moving from east to west.
