How long was an early Earth year? Roughly how long did it use to take for the early Earth 4.5~ billion years ago to complete one revolution around the Sun?

(I know the Earth was spinning much faster, so a day would only take 2-3 hours, so I'd like to have the answer in terms of current Earth days for better understanding - if possible.)

(I Google'd the heck out of this question and couldn't find an answer.)
There are two components to take into account for this question

the earth rotation rate on itself
the orbiting period around the sun

A day back then was shorter than today's earth day. The earth was rotating quicker in the past, but its rotating period around the sun didn't change much because of Kepler's law.
I cannot say how it was 5 billion years ago (anyway, did the earth had something you could call a surface to track the day from then?), but you could find data derived from fossils analysis for the last billion years, e.g. here from Nasa's SpaceMath, on how long a day was back then - I realize now the figures below assume the orbiting period of the earth around the sun (~8766 hours) stayed constant over this period of time. This assumption is wrong as explained here - however stating it &quot;has been close to its current value for the last 2-3 billion years&quot;, so below figures are an approximation

From which I would roughly interpolate: 600 days earth self-rotation per year full rotation around the sun 2 billion years ago

Edit
We are saying here that earth was rotating quicker in the past:

Detailed  studies  of  fossil  shells,  and  the  banded  deposits  in  certain  sandstones,  reveal a much different length of day in past eras! These bands in sedimentation and  shell-growth  follow  the  lunar  month  and  have  individual  bands  representing  the  number  of  days  in  a  lunar  month.
By  counting  the  number  of  bands,  geologists can work out the number of days in a year, and from this the number of hours  in  a  day  when  the  shell  was  grown,  or  the  deposits  put  down.  The  table  above shows the results of one of these studies.
