Our day is shaped in various ways by the spinning of events, whether it’s the Earth rotating around the Sun, or the shift workers switching between the night and day. Certain of these events occur every day, while others are less predictable and more unpredictable.

Most people know that the Earth revolves every 24 hours around the Sun. But what isn’t as well-known is the speed at which the Earth rotates can vary and make days appear shorter or longer than what is expected. This is the reason why Atomic clocks that provide standardized time must be periodically adjusted by adding or subtracting seconds. This is referred to as a leap second.

Precession is a typical rotational event. It is the cyclical wobble in the Earth’s axis. It’s like a spinning toy top that is slightly off-center. This axial shift relative to fixed stars (inertial space) is a time period of 25,771.5 years, and is the cause of a variety of weather conditions patterns, such as the shifting direction of cyclones across the Northern and Southern hemispheres.

Scientists have also observed that the speed at that the Earth is rotating slows down over long periods of time, causing the solar days to grow longer. On June 29 the world added a leap second to the atomic clocks to better align them with the rotation of the Earth. While the addition of a single second might seem like a small amount but it has significant implications for businesses that depend on changing schedules and rotating times. For instance multinational companies that rely on employees from all over the world, fumbling through static wiki pages and spreadsheets to manage the changing schedules of calls can easily become expensive in terms of revenue and company reputation. On-call rotation software is becoming popular as it reduces interruptions to services and also manages the transfer coverage and allows employees to be more transparent.
