Question

At which Longitude does the date change?

Answer 1

Hint: Longitude is a geographic coordinate that describes the east-west position of a point on the Earth's surface or a celestial body's surface. It is an angular measurement symbolised by the Greek letter lambda ().

Complete answer:
"On the "180° longitude meridian," the date changes. It is an "imaginary line" on the surface of the earth that goes from the North Pole to the South Pole" and is also known as the "International Date Line" (IDL). The relationship between the dateline and the time in a day is defined by this line. The midnight line, the meridian directly opposite the sun, also divides two days and dates.

The International Date Line (IDL) runs between the US-controlled Aleutian Islands and the Russian-controlled "Commander Islands."

The first is that the ‘grid' of latitude and longitude remains ‘fixed' while the earth underneath it moves. As a result, a spot on the ground's latitude and longitude fluctuate throughout time. This is a map of the NGS-managed Continuously Operating Reference Stations.

Because time zone boundaries do not always match with meridians, the times are approximate. The distinction between night and day is only illustrative; daylight hours vary depending on latitude and season.

Note: For legal, commercial, and social purposes, a time zone is a region that observes a uniform standard time. Because it is more practical for locations in frequent communication to preserve the same time, time zones tend to follow the borders of countries and their subdivisions rather than rigidly following longitude.
