The counting of days on earth starts at what location?
The counting of days on earth starts at the Prime Meridian, which is a line of longitude at 0 degrees located in Greenwich, London. This is known as Greenwich Mean Time (GMT) and serves as the reference point for keeping time worldwide.
What 2 days have 12 hours of sunlight and 12 hours of dark?
first day of winter,[Jan 21ish] and first day of summer [July 20ish] I think
And, you would be WRONG! Those dates are for Summer and Winter solstice. The days of equal length are called the...?(wait for it...) EQUINOX! March 20 and September 22, roughly.
How are space and time related?
To understand this claim easier, know the formula, d rt, which means "distance equals rate times time." It takes time to move a distance. If time was frozen, then space would also be frozen, and vice-versa; you couldn't grow up or move around. This is why freezing time or traveling at lightspeed is difficult.

Who used the sun to measure time?
Everyone always has, and we still do. Now, in modern times, we have a machine designed to turn around once in exactly the same time as it takes the sun to turn around once in the sky. It has a thing on it to display what part of the cycle the sun is in. In order to be able to talk about it with other people, we place a standard set of marks all around the display-thing so we can refer to the number of marks, and the orher person knows what point in the cycle we're talking about. But the basic idea of the machine is to match the cycle of the sun. If my machine doesn't match the sun's daily motion pretty close, I have to quickly find another machine that's still running properly, or else I can refer back directly to the sun to get a rough idea of how many marks we're at. If I don't do one or the other pretty quick, I'm going to be early or late for all my appointments.
What is the calendar you use today called?
The Gregorian calendar is the most widely used calendar system in the world today. It was introduced by Pope Gregory XIII in 1582 as a reform of the Julian calendar.
How many minutes are in 100000000 hours?
There are 60 minutes in 1 hour. Therefore, to calculate the number of minutes in 100,000,000 hours, you would multiply 60 by 100,000,000 to get 6,000,000,000 minutes.
Were the days of the week named after gods?
Sunday and Monday were named after the sun and the moon. Tuesday, Wednesday, Thursday, and Friday were named after Norse gods Tiu, Woden, Thor, and Frigg (or Frija), and Saturday was named after the Roman god Saturn.
Why does a day have 24 hours not 10?
It's a more or less arbitrary choice made a long time ago, and it would cost a lot to replace all the clocks. There have been some attempts to go to a decimal system for time, but they simply haven't caught on.
What time zone is furthest west?
The western-most point of the International Date Line is around the west end of the Aleutian Islands of Alaska, USA, which are in Hawaii-Aleutian Standard Time (UTC-10) from November to March and Hawaii-Aleutian Daylight Saving Time (UTC-9) from March to November. However, although that is the time zone that is farthest west, it is not the farthest behind UTC. Samoa Standard Time (SST) and Niue Time (NUT) are UTC-11. Baker and Howland Islands are in UTC-12, but they are officially uninhabited.
What time is it in Boston if it is 8pm in Zimbabwe?
Boston is 6 hours behind Zimbabwe, so if it's 8pm in Zimbabwe, it would be 2pm in Boston.
What limitations did the sundial have?
1. Can only tell the time, not the date. 2.Obviously needs sun, not clearly viewable on a cloudy/dark day. 3. Needs to be in a certain position in order to be accurate.
How many seconds in a melinemum?
I was confused at first, unable to decide whether a "melinemum" is the least value
of a function or a spinal X-ray with contrast. Eventually, I guessed that it's intended
to suggest the period of 1,000 years ... a 'millenium'.
1 day = 86,400 seconds

The hands of a clock rotate either clockwise or counterclockwise to indicate the time. The minute hand moves 360 degrees in one hour, while the hour hand moves 30 degrees in one hour. The direction of rotation depends on whether the time is increasing or decreasing.
Night time typically starts around sunset, which is when the sun goes below the horizon. This varies depending on your location and the time of year. Night time generally continues until sunrise the following day.
