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.

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.
Which are the planet which rotate around the earth depends on the rotation of clock?
The only natural object that moves around Earth is the Moon - and for this very reason it is not considered a planet. Rotation does not depend on clocks.
Why is the moon not seen on new moon day?
Because the moon is between the sun and the earth. During a new moon, you see the shadow of the moon, usually against a daytime sky, which makes the moon virtually invisible without a telescope.
What time of day does the new moon phase occur during the period of a 24 hour day?
The New Moon phase occurs once every 29.53 days. At the moment when it occurs, the clocks in each time zone on earth read a different hour.
Describe the characteristics of the moon and the Earth for each phase of the moon?
The characteristics of the Earth and Moon don't depend on the Moon's phase.The thing that changes is their orientation relative to the sun. In fact, theMoon's phase is the result of that orientation.New Moon . . . Earth, Sun, and Moon in line, with Moon in the middle.Crescent . . .

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.
Why are you setting clocks back a week later this year?
I don't know but its just different or something to do with the moon or Earth
What does astonomy have to do with calendars?
Years and months are determined by how long the Earth takes to orbit the Sun for years, and how long it takes the Moon to orbit Earth for months. Astronomy is concerned with studying the Earth, Sun and Moon, along with other things in space.
What are calendars of the moon?
You can find moon calendar for year 2010 at calendarlabs.com
What do you use to measure and tell time?
Obelisk, Sundial, Merkhet, water clock, escapement, quartz clocks, atomic clocks, wrist watch, the sun, and a microwave are just a few.
What is a 'new moon'?
New Moon is nothing but the lunar phase that occurs when the Moon, in its monthly orbital motion around Earth, lies between Earth and the Sun, and is therefore in conjunction with the Sun as seen from Earth. At this time, the illuminated half of the Moon faces directly toward the Sun, and the dark or unilluminated portion of the Moon faces directly toward Earth, so that the Moon is invisible as seen from Earth. New Moon is often considered to occur at the time of the appearance of the first visible crescent of the Moon, after conjunction with the Sun. This takes place over the western horizon in a brief period between sunset and moonset, and therefore the precise time and even the date of the appearance of the New Moon by this definition will be influenced by the geographical location of the observer. The astronomical New Moon, sometimes known as the dark moon to avoid confusion, occurs by definition at the moment of conjunction in ecliptic longitude with the Sun, when the Moon is invisible from the Earth. This moment is unique and does not depend on location, and under certain circumstances it may be coincident with a solar eclipse. The New Moon is the beginning of the month in lunar calendars such as the Muslim calendar, and in lunisolar calendars such as the Hebrew calendar, Hindu calendars, Buddhist calendar, and Chinese calendar. == ==
Is there life on Moon or Mars?
There is no life on the Moon or Mars. The unique planet on the solar system that has gathered conditions to develop life is the Earth.
Which are the planet which rotate around the earth depends on the rotation of clock?
The only natural object that moves around Earth is the Moon - and for this very reason it is not considered a planet. Rotation does not depend on clocks.
What all things come in calendars?
Days, dates, national holidays, some calendars have things like the moon cycles on them. Some calendars show multiple years
How long does it take for the moon to finish its circulation around Earth?
28 days. When viewed from the earth, the moon goes through phases. It starts out as a "full moon" and then as you watch it each night you see it get smaller and smaller until it disappears and then it returns back. These phases are shown on many Calendars, so you can refer to a calendar to study the orbit of the moon.
Is your calendars based on earth's orbit of sun or the Moon's orbit of earth?
Most calendars are based on the Earth's movement round the Sun. The Gregorian calendar is used in most countries and it has 365 days in a year, with an extra day (February 29) in 97 years out of every 400, which are called leap years. This gives an average year of 365.2425 days.
