Why the positions of earth and the sun were used to develop calendars and clocks?

Why arethe positions of earth and the sun used to develop calendars and clocks?
Because they are useful for predicting the future. Primitive people in the tropics have no real need for calendars; the weather doesn't change all that much from day to day. In the temperate zones, it's important to know when to plant, and when to harvest, and when to expect recurrent events. One of the earliest calendars we know of was used to keep track of the seasons along the Nile River in Egypt; if you knew approximately when the Nile floods would occur each year (and they are fairly predictable!) then you knew more or less when to move to higher ground and when it might be safe to return.
Which is used for our clocks Sidereal or solar day?
Solar day is typically used for our clocks and calendars, as it is based on the Earth's rotation relative to the sun. Sidereal day, on the other hand, is based on the Earth's rotation relative to distant stars.
What is a leap minute?
A Leap Minute is a minute that is added or removed according to what's needed to keep our clocks and calendars in synch with the movement of our planet and the sun. The movement of the Earth around the Sun, and around its own axis, doesn't match up exactly to our clocks and calendars. To prevent the error from growing year after year, Leap days, leap hours, leap minutes, even leap seconds, are regularly added to keep everything in synch.
Does time exist in Greenland?
Yes, time exists in Greenland just like it does in any other place on Earth. Greenland follows the same time zones as other regions, and people there use clocks and calendars to measure time.
What are calendars based off of?
Calendars are based off of the solar system and how the Earth revolves around the sun.
What motion of your earth causes 1 year on your calendars?
One orbit of the Earth around the Sun.
Which area of Earth Science was involved in producing the first calendars?
Astronomy
Where can one buy tide clocks?
A tide clock is a special clock that keeps track of the Moon's motion around the Earth. These types of clocks may be purchased from Amazon, Tidal Clocks and Coastal Tide Clocks.
Who controls the time and how does it impact our daily lives?
Time is controlled by the Earth's rotation and orbit around the sun, as well as by man-made systems like clocks and calendars. The concept of time impacts our daily lives by organizing our schedules, determining when events occur, and influencing our sense of urgency and productivity.
What are the three different calendars names thoughout history?
The three primary types of calendars are the solar, lunar and lunisolar. Calendars that are based on the earth's revolution around the sun without regard for the moon's monthly cycle, like the Gregorian calendar used in most if not all Christian countries, are called solar calendars. Calendars that are based only on the moon's revolution around the earth without compensation for the seasonal effects of the earth's solar orbit, like the Hijra used in Islamic countries, are called lunar calendars. Lunisolar calendars, like the Jewish calendar, have months that start at the times of the new moon but also periodically (seven times every nineteen years) add leap months in an attempt to stay in sync with the solar cycle as well.
How the earth moon and sun were used to develop clocks and calendars?
The time it takes for the Earth to rotate is close to, but not exactly 24 hours, being about 4 minutes short of it. The time the Earth takes to orbit the Sun is about 365.25 days. The Moon takes about 27.3 days to orbit the Earth. These things give us our day, year and month. As the Earth is orbiting the Sun, as well as rotating, the "solar day" is exactly 24 hours. This is because we divide the solar day into 24 hours, of course. The year is set at 365 days, so we need the leap years of 366 days. The Moon's phases take about 29.5 days to complete, again because the Earth is orbiting the Sun as well as rotating. We have months of various lengths, but they still don't fit exactly with the cycle of the Moon's phases. Some calendars such as the Islamic calendar are based on the Moon's cycle. Unfortunately 12 "lunar months" are about 11 days short of the time it takes Earth to orbit the Sun.
