When is Leap Second Time Adjustment Day?
Sunday December 31stLeap Second Time Adjustment Day is listed as a commemoration only.. Scientists who have lived for many years do not make changes. However, if they do, it will be done on either June 30 or December 31.
The majority of the world's time is purely based on a 24-hour day in which each hour contains 60 minutes, and each minute contains 60 seconds. That measurement is much too simple for accurate time measurement.
Scientists have attempted to convert the hours of the day into a reliable and precise way of measuring since about 140 AD. Measurement of the 24 hour day is not a precise science due to the Earth's rotation's variability. There is some doubt about the legitimacy of leap second adjustments. Scientists who have lived for many years do not make changes. However, if they do, it will be done on either June 30 or December 31. Scientists have increased 27 leap seconds between 1972 and 2020 between 1972 and 2020. The fact that the Earth's rotation is slowing also affects the atomic clock, which means the length of our day is getting longer. Scientists found that no leap second was required in 2020. No leap second was needed.
