When is Leap Second Time Adjustment Day?
Sunday December 31stLeap Second Time Adjustment Day is listed as a commemoration only. Scientists who have been around for many years do not make changes. But, if they do, it's either June 30 or December 31.
The majority of the world's time is based on a 24-hour day in which each hour contains 60 minutes, and each minute contains 60 seconds. The measurement is much too simple for accurate time measurement.
Scientists have attempted to convert the hours of the day into a standardized and precise way of measuring since about 140 AD. The 24 hour day measurement is not an exact science due to the Earth's rotation's constant variability. The validity of leap second adjustments is being questioned by some. Scientists who have been around for many years do not make changes. But, if they do, it's either June 30 or December 31. Scientists have gained 27 leap seconds between 1972 and 2020. The fact that the Earth's rotation is slowing is another factor that is affecting the atomic clock, which means the length of our day is getting longer. Scientists found that no leap second was required in 2020.
