It’s the world spinning around the Sun or shift workers shifting between days and nights our lives are shaped by many spinning events. Some of these events occur every day while others are less predictable and more irregular.
Most people are aware of the fact that the Earth revolves around 24 hours around the Sun. What is less well known is that the speed at which Earth rotates may vary making a day appear shorter or longer than you would expect. This is why atomic clocks that keep a standard time must be periodically adjusted by adding or subtracting seconds. This is referred to as leap seconds.
One of the more frequent periodic events that rotate is precession, which is the cyclical wobble of Earth’s axis for rotation similar to a spinny, slightly off-center spinning toy top. This Axial shift in relation to fixed stars (inertial spaces) has a duration of 25,771.5. It is the cause for a myriad of weather patterns such as the alternating directions between cyclones in the Northern and Southern Hemispheres.
Scientists have also observed that the speed of Earth rotation slows down over time, which causes solar days to get longer. On June 29th, the world added an extra leap second to the atomic clocks to better align them with the axis of the Earth. While the addition of one second may seem like a minor thing but it can have significant implications for businesses that rely on changing schedules and rotating times. For multinational businesses with a global workforce, managing changing call schedules by fumbling through spreadsheets or static wiki pages can be costly in terms of reputation and revenue. This is why more and more companies are using on-call rotation software to decrease interruptions in service and manage the coverage of transfers and give employees a better understanding of the process.
