SUMMARY

The Earth's rotation period varies daily due to factors such as seasonal winds and tides, with changes occurring on the order of nanoseconds. The International Earth Rotation and Reference Systems Service (IERS) is a primary source for this data, although live updates may not be readily available on their website. Additional resources include Time and Date's Earth Rotation page, which provides relevant information. For precise calculations, the angular frequency of Earth can be determined using the formula ω=2(pi)/86400, yielding a value of approximately 72.7221 x 10^-6.

PREREQUISITES
  • Understanding of Earth's rotational dynamics
  • Familiarity with the International Earth Rotation and Reference Systems Service (IERS)
  • Basic knowledge of angular frequency calculations
  • Experience with online data sources for scientific information
NEXT STEPS
  • Explore the IERS website for Earth rotation data products
  • Research the impact of seasonal winds on Earth's rotation
  • Learn about tidal forces and their effects on rotation
  • Investigate additional online resources for real-time Earth rotation metrics
USEFUL FOR

Geophysicists, meteorologists, astronomers, and anyone interested in the dynamics of Earth's rotation and its variations.

The period of rotation of the Earth around itself is changed by seasonal winds, tides, and other factors. The exact amount changes daily(about nano second). Is there a website that shows this amount?

I imagine there are lots of websites that contain this information. For example:

https://www.timeanddate.com/time/earth-rotation.html

If you try an Internet search you should find plenty of others.

I want angular frequency of Earth at this moment but I can't find it on Google
ω=2(pi)/86400=72.7221*10^-6 (difference every moment)

I can't remember now. It was something obvious like "length of a day".
