If it’s the Earth rotating around the Sun or shift workers who switch between nights and days our daytime is formed by a myriad of rotating events. Some of them happen every day but others are more irregular and unpredictable.
Most people know that the Earth revolves around 24 hours around the Sun. But what isn’t as well-known is that the speed at which Earth rotates can vary, making the day appear to be longer or shorter than expected. This is the reason why Atomic clocks that provide standardized time have to be periodically adjusted by adding or subtracting seconds. This is referred to as leap seconds.
One of the more regular rotational events is precession which is the cyclical wobble that occurs on the Earth’s axis which is similar to a slightly off-center spinny toy top. This axial shift in relation to fixed stars (inertial space) has a duration of 25,771.5 years, and is responsible for various weather patterns, including the changing direction of cyclones in the Northern and Southern hemispheres.
Scientists have also noticed that the speed of Earth rotation slows over time, causing solar day to become longer. This is the reason why, on June 29 the world added a leap second to atomic clocks so that they could be more in line with the real-world Earth’s rotation. While the addition of one second may seem small but it could have a significant impact for businesses that depend on changing schedules. For instance multinational companies that depend on employees from all over the world, fumbling through static wiki pages and spreadsheets to manage changing call schedules can quickly become costly in terms of revenue and company reputation. On-call rotation software is becoming popular because it cuts down on interruptions to service and helps manage transfer coverage and provides transparency for employees.
