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

Most people know that the Earth revolves every 24 hours around the Sun. However, what is not as well-known is that the speed at which Earth rotates is variable which can make days appear shorter or longer than what is expected. The atomic clocks, which maintain an uniform time, need to be adjusted frequently by adding or subtracting https://northcentralrotary.org/2020/02/17/creating-a-barrier-free-space-for-people-with-disabilities/ a second. This change is called leap seconds.

Precession is a common rotational event. It is a oscillation of the Earth’s axis, which is similar to a toy top spinning that is slightly off-center. This axial shift in relation to fixed stars (inertial spaces) has the duration of 25,771.5. It is responsible for a variety of weather patterns such as the alternating direction between cyclones on the Northern and Southern Hemispheres.

Scientists have also noticed that the speed of Earth is slowing over time, leading solar day to become longer. That’s why on June 29 the world added one second leap to atomic clocks in order that they would be more in sync with the actual rotation of our planet. While the addition of a single second may seem like a minor thing, it has important implications for businesses that rely on rotating alter schedules. For multinational companies with a global staff managing the changing schedules of calls using static wiki pages or spreadsheets can be costly in terms of revenue and reputation. On-call rotation software is becoming popular because it cuts down on service interruptions, manages transfer coverage, and allows employees to be more transparent.
