The international date line zig-zags to avoid intersecting land.
Greenwich
Because the meridian cuts through some inhabited island groups, and other geopolitical locations. IF the meridian itself were determined to be the dateline, then these places would suffer the problem of having part of their territory in one date zone, and part another date zone. Some sections of the actual dateline has been arbitrarily relocated to provide unified date and time for these locations.
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.
It doesn't. The Prime Meridian is exactly zero longitude over its entire 12,000+ milesbetween the north and south poles.The International Date Line was drawn with zigs and zags in it, rather than straightalong the meridian of 180° longitude, in order to avoid splitting any single country,state, or island into two different calendar dates.
The International Date Line is nominally the line of 180 degrees longitude, both east and west ...exactly opposite the Prime Meridian and half-the-earth away from it.The Line was drawn with some jogs and zig-zags in it for political reasons, mainlyto avoid splitting island nations or contiguous areas of national interest.It's so difficult getting to meetings and dental appointments on time as it is now.Can you just imagine what it would be like if there were two different calendardates on opposite sides of the same town or island ?
No, the prime meridian and equator are not warm places in themselves. The prime meridian is an imaginary line that marks 0° longitude and passes through Greenwich, England. The equator is an imaginary line that marks 0° latitude and circles the Earth halfway between the North and South Poles. The temperature at these locations can vary depending on the climate of the region they pass through.
So that the entire continent, country, state, providence, island(s), etc, can be in the same time zone.
The prime meridian is a line of longitude, not a specific location. Therefore, it does not have a specific temperature. Temperatures along the prime meridian will vary depending on the actual location on the line.
That was done in order to avoid splitting any single country, island group, or state into two different calendar dates. If the IDL had followed the 180° meridian exactly, one of the island groups that would have been affected is the Aleutian chain. Had the line not jogged, then the state of Alaska, and therefore the USA, would have always had two different calendar dates going on within its borders.
So that the entire continent, country, state, providence, island(s), etc, can be in the same time zone.
Greater Meridian Time is a concept used in acupuncture to refer to the peak hours of energy flow in the body's meridians. This time is believed to vary for each meridian and is thought to influence the treatment's effectiveness. Practitioners may take into consideration the Greater Meridian Time when scheduling acupuncture sessions for optimal results.
It is sunny in many places today, but the specific location can vary. You can check a weather website or app for the most up-to-date information on sunny locations.
