This doesn't happen every year. It is due to happen in 2008. The last one was in 2005. It is the same as why we have a leap day every 4 years. A year is about 365.25 days long, not 365 days. To make up for that, we add a day every 4 years. A leap second is added to keep time accurate, as the rotation of Earth is slowing. Otherwise our time would become out of synch with the way the Earth rotates and orbits the Sun. There are a number of factors determining how we measure time, because of the way Earth is both rotating and orbiting the Sun, and doing so at slightly different speeds.

What is used in making atomic clocks that lose one second every 300 years?
Cesium atoms are commonly used in making atomic clocks, as they are extremely consistent in their oscillation frequencies. By measuring the vibrations of cesium atoms, atomic clocks can maintain extremely accurate timekeeping, losing only about one second every 300 years.
What kind of clock offers the most precise?
Atomic clocks are the most accurate clocks that are available to the general public. To date, the most accurate clock made is the so-called quantum logic clock, which is accurate to about one second in 3.7 billion years.
What element is used to make very accurate atomic clocks?
Cesium is used to make very accurate atomic clocks. The oscillation frequency of radiation emitted by cesium-133 atoms is used to define the second in the International System of Units (SI).
How can international time-standard clocks be regulated by atomic vibrations that are accurate to 1 second on 80 million years?
The best of these are currently the 'cesium fountain' atomic clocks in which the cesium atoms, and their atomic spectral emissions, is cooled to close to absolute zero (to minimise thermal effects). These can reach stability of the order of 3 parts in 10(-16). The atomic clock at NIST in the US is of this type. (And in UK, and France etc.) Which is equivalent to an uncertainty of 1 second in 100 million years.
Why is atomic clock used?
Atomic clocks are used because they are incredibly accurate and precise timekeeping devices. They rely on the vibrations of atoms to measure time, which is highly stable and consistent. This makes atomic clocks essential for applications that require precise time synchronization, such as global navigation systems, telecommunications, and scientific research.
What element is used to make atomic clocks?
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.

Cesium atoms are commonly used in making atomic clocks, as they are extremely consistent in their oscillation frequencies. By measuring the vibrations of cesium atoms, atomic clocks can maintain extremely accurate timekeeping, losing only about one second every 300 years.
The Second is the unit of Time adopted by the International System of Units in France What chemical element is used to measure a 'second' with an accuracy better than one second in six million years?
Cesium is the chemical element used in atomic clocks to measure a second with high accuracy. Atomic clocks use the natural resonance frequency of the cesium atom to define the length of a second. This level of precision allows atomic clocks to keep time accurately to within one second in several million years.
Used in the making of atomic clocks that lose one second every 300 years?
Cesium atoms are commonly used in the making of atomic clocks due to their consistent oscillation frequencies. These clocks measure time by counting the cycles of radiation emitted by cesium atoms, which allows for extremely accurate timekeeping over long periods. Due to cesium's stable and predictable behavior, atomic clocks using cesium technology only lose about 1 second every 300 years.
Who invented the atomic clock?
The first atomic clock was invented in 1948 by the US Bureau of Standards.The first practical atomic clock was invented by English physicist Louis Essen in the 1955.Atomic clocks use the energy changes that take place in atoms to keep track of time. Atomic clocks are so accurate that they lose or gain no more than 1 second once every 2 or 3 million years.The most accurate, modern-day atomic clocks will neither lose nor gain a second in 168 million years.
What kind of clock offers the most precise?
Atomic clocks are the most accurate clocks that are available to the general public. To date, the most accurate clock made is the so-called quantum logic clock, which is accurate to about one second in 3.7 billion years.
What is the difference between mechanical clock and atomic clock?
Atomic clock is faster than mechanical clock and it is the most accurate of all clocks in the world.

Cesium is used to make very accurate atomic clocks. The oscillation frequency of radiation emitted by cesium-133 atoms is used to define the second in the International System of Units (SI).

Which is the most accurate measurement of time?
The most accurate measurement of time is provided by atomic clocks, which are based on the vibration of atoms, such as cesium or rubidium. These clocks are used as the international standard for timekeeping and are incredibly precise, losing only a second every few million years.
Which kind of clock is accurate to within one second in 1.7 million years?
An atomic clock utilizing the vibrations of atoms such as cesium or rubidium is accurate to within one second in 1.7 million years. These clocks are extremely precise due to the consistent frequency of atomic transitions.
How much do telemarketers make an hour?
In 1967, an atomic standard was adopted for second, the SI unit of time. One standard second is defined as the time taken for 9 192 631 770 periods of the radiation corresponding to unperturbed transition between hyperfine levels of the ground state of cesium - 133 atom. Atomic clocks are based on this. In atomic clocks , an error of one second occurs only in 5000 years. From 60 sec is 1 min from this 60 minutes is hour
