Important Events of December – 31

Leap Second Time Adjustment Day

The majority of the world measures time solely 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 since about 140 AD have attempted to break down the hours in the day into a consistent and precise means of measure.
Due to the variability of the Earth’s rotation, measurement of the 24 hour day is not an exact science.
There is some dispute over the validity of leap second adjustments.
The leap-second system was first introduced in 1972.

There are over 1,500 national days. Don’t miss a single one. Celebrate Every Day with “Exams Daily”

Makeup Your Mind Day

Make Up Your Mind Day is observed annually on December 31st.
This day is set aside to encourage us to quit wavering, to take a side, to follow through with a decision and stick to it.
As New Year’s resolutions go, this may be the day to decide which ones to declare.
Make Up Your Mind Day is the incentive to make a choice.
