Leap seconds are occasional one-second adjustments added to Coordinated Universal Time (UTC) to synchronize atomic time with astronomical time due to Earth's irregular rotation. These adjustments ensure that our clocks remain in close alignment with the position of the sun in the sky, maintaining the accuracy of timekeeping systems worldwide.

one-second adjustments

Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time, serving as the basis for civil time across the globe. It is maintained using highly precise atomic clocks and is periodically adjusted with leap seconds to account for Earth's irregular rotation.

Coordinated Universal Time

Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time, maintaining a uniform time across the globe. It is not adjusted for daylight saving time and is the basis for civil time in many countries, ensuring synchronization in global communications and data exchange.

synchronize atomic time

Astronomical time is a concept used to describe the measurement of time based on the Earth's rotation and its orbital path around the Sun, providing a means to maintain precise synchronization with celestial events. It is crucial for various scientific purposes such as navigation, astronomy, and understanding the Earth's natural cycles and seasonal changes.
