I How Does Earth's Rotation Vary Daily?

[abdossamad2003]

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?

Your best bet is the International Earth Rotation and Reference Systems Service, but a quick glance at their website didn't show me any live data.

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.

What did you search on Google that led to this result?

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".
