The Prime Meridian is the most important line of longitude. It is located at zero degrees longitude (0˚). The Prime Meridian runs through Greenwich, a place near London. It is the starting point for numbering meridians.
Which is the longest parallel?
The equator is the circle that is equidistant from the North Pole and South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only ‘great circle’ (a circle on the surface of the Earth, centered on Earth’s center).
Is the latitude?
Latitude measures the distance north or south of the equator. Lines of latitude, also called parallels, are imaginary lines that divide the Earth. They run east to west, but measure your distance north or south. The equator is the most well known parallel.

What is UTC date?
UTC() takes comma-delimited date and time parameters and returns the number of milliseconds between January 1, 1970, 00:00:00, universal time and the specified date and time.
