It takes 10 seconds for the earth to revolve 360 degrees at 6: 09 in 365 days, which is called the sidereal year.

What you said at 5: 48: 46 on 365 is called the Tropic of Cancer, which is the time when the sun makes periodic round-trip motion on the Tropic of Cancer. As a regression motion, it is called the direct point of the sun.
