Our day is shaped in many ways by the spin of events whether it’s the Earth’s rotation around Sun, or the shift workers who switch between days and the nights. Some of these happen every day, while others are more irregular and unpredictable.

Most people know that the Earth rotates 24 hours a day around the Sun. The thing that is less well-known is the speed at which Earth rotates can vary and make days appear longer or shorter than expected. The Atomic clocks, that maintain an uniform time, need to be adjusted regularly by adding or subtracting seconds. This is referred to as a leap second.

Precession is a normal rotational event. It is the periodic wobble on Earth’s axis. It’s like the spinning top of a toy that is a little off-center. This axial shift in relation to fixed stars (inertial spaces) has the duration of 25,771.5. It is responsible for a myriad of weather patterns for example, the alternating direction between cyclones in the Northern and Southern Hemispheres.

Scientists have also observed that the speed at which the Earth rotates slows down over long periods of time, which causes solar days to become gradually longer. This is the reason why, on June 29th the world added an extra second to atomic clocks in order that they could better match up with the actual global rotation. While one second may seem minor but it could have a significant impact for businesses who rely on changing schedules. For example, for multinational companies that rely on an international workforce, fumbling through static spreadsheets and wiki pages to manage changing call schedules can quickly become costly in terms of revenue and reputation. On-call rotation software is becoming more popular as it reduces interruptions in service and also manages the transfer coverage and gives employees https://northcentralrotary.org/2021/12/06/advertising-at-rotary-events a clearer picture of the situation.
