Year (Leap)

A leap year is a year that has 366 days, including an extra day (February 29) added to keep the calendar year synchronized with the astronomical year.

History/Origin

The concept of adding an extra day to the calendar was introduced by the Julian calendar in 45 BC and refined by the Gregorian calendar in 1582 to correct inaccuracies in the Julian system, establishing the current rules for leap years.

Current Use

Leap years are used in the Gregorian calendar to maintain alignment with Earth's orbit around the Sun, occurring every four years with exceptions for century years not divisible by 400, ensuring calendar accuracy over long periods.


Millisecond

A millisecond (ms) is a unit of time equal to one thousandth of a second.

History/Origin

The millisecond was introduced as a standard unit of time measurement with the development of precise timekeeping and scientific instrumentation in the 20th century, particularly with the advent of electronic clocks and digital technology.

Current Use

Milliseconds are widely used in computing, telecommunications, and scientific measurements to denote very short durations, such as in data processing, network latency, and high-frequency trading.
