Because the Headquarters of the Admiralty, the British Royal Navy, were in Greenwich, SE London, when the measurement of Longitude was discovered.
All of the world's time zones are either earlier or later than the Prime Meridian. (GMT - Greenwich Mean Time 0 degrees longitude).
Because that's where the Royal Observatory was.
1784
The time meridian is each standard time zone roughly centered on a line of longitude exactly divisible by 15 degrees and the prime meridian is the starting point for the standard time zones an arbitrary longitude line.
-- The longitude of the Prime Meridian is zero. -- Every point on the Prime Meridian has a different latitude. -- For every possible latitude, there is a point on the Prime Meridian.

Halfway between the Prime Meridian and 80 degrees west has to be pretty close to 40 degrees west, we'd say.
This is called the Prime meridian, it passes through Greenwich, England.

The Prime Meridian is 1/2 of the boundary between the eastern and western hemispheres.

The Prime Meridian, ie 0 degrees longitude, runs through the London suburb of Greenwich.
Halfway between the Prime Meridian and 80 degrees west has to be pretty close to 40 degrees west, we'd say.
This is called the Prime meridian, it passes through Greenwich, England.
The main difference between the eastern and western hemispheres is their geographical location. The eastern hemisphere includes parts of Africa, Asia, Europe, and Australia, while the western hemisphere includes parts of North and South America. Additionally, the eastern hemisphere is often associated with older civilizations and cultures, while the western hemisphere is known for its more recent history of colonization and globalization.
Prime meridian is used to fix the world standard time.
